The difference between brass, tin bronze purple copper

Pure copper is a rose-red metal, the surface is purple after the formation of copper oxide film, so industrial pure copper is often called purple copper or electrolytic copper. Density of 8-9g/cm3, melting point 1083 ° C. Pure copper conductivity is very good, a large number of wires, cables, brushes, etc.; good thermal conductivity, often used to manufacture magnetic instruments, instruments that must be anti-magnetic interference, such as compasses, aviation instruments, etc.; plasticity is very good, easy to hot pressing and cold pressure processing, can be made into tubes, bars, wires, strips, strips, plates, foils and other copper.

Brass is an alloy of copper and zinc. The simplest brass is copper – zinc binary alloy, called simple brass or ordinary brass tube. Different mechanical properties of brass can be obtained by changing the zinc content of brass. The higher the zinc content in brass, the higher its strength and slightly lower its plasticity. The zinc content of brass used in industry does not exceed 45%, and a higher zinc content will produce brittleness and deteriorate the performance of the alloy.

Tin bronze is one of the earliest alloys used in history, originally referred to as copper-tin alloy, because the color is greenish gray, so called bronze. Tin bronze has high mechanical properties, good corrosion resistance, friction reduction and good casting properties; low sensitivity to superheat and gas, good welding properties, non-ferromagnetic, and small shrinkage coefficient. Tin bronze has higher corrosion resistance than brass in the atmosphere, seawater, freshwater and steam.

Sleeve Bearing

Also known as a brass bearing, brass bushing are used for movement between two parts whose purpose is to limit friction and any potential vibration. An important feature is that they can withstand high temperatures & self-lubricating.

Flange Bearing

The purpose of flanged brass bushings is to allow rotation within a contained area. One is bolted inside a housing unit while the other is not attached. They are best used for lighter-duty jobs.

Thrust Washer

Thrust washer are also called thrust washers and they are for rotation needs. They rotate along moving parts.

Introduction to the knowledge of various copper alloys

Brass

Brass is a copper alloy of copper and zinc, named because of its yellow color. Brass has good mechanical properties and wear resistance, and can be used to make precision instruments, parts of ships, shells for guns, etc. Brass sound good, so gongs, cymbals, bells, horns and other musical instruments are made of brass.

Nautical brass

It is an alloy of copper, zinc, and tin, and is resistant to seawater erosion, so it can be used to make parts for ships and balancers.

Bronze

The alloy of copper and tin is called bronze, so named because of its green color. Bronze generally has good corrosion resistance, wear resistance, castability and excellent mechanical properties. It is used in the manufacture of precision bearings, high-pressure bearings, mechanical parts on ships that resist corrosion by seawater, and various plates, tubes, and bars. Bronze also has a perverse characteristic – “heat shrinkage and cold expansion”, which is used to cast statues and expand after cooling, which can make the brow clearer.

Phosphor Bronze

An alloy of copper with tin and phosphorus. It is hard and can be used to make springs.

White copper

White copper is an alloy of copper and nickel, its color is the same as silver, silver shining, not easy to rust. Commonly used in the manufacture of electrical appliances, instruments and decorative items.

The natural characteristics of copper alloy

Copper metal, element symbol Cu, atomic weight 63.54, specific gravity 8.92, melting point 1083oC. Pure copper is light rose or light red, the appearance of copper oxide film, the appearance of purple copper. Copper has many valuable physical and chemical properties, such as its high thermal and electrical conductivity, chemical stability, high tensile strength, easy to fuse, with corrosion resistance, plasticity, ductility. Pure copper can be drawn into very fine copper wire and made into very thin copper foil. It can be alloyed with zinc, tin, lead, manganese, cobalt, nickel, aluminum, iron and other metals.

The development of copper alloy exercise technology has gone through a long process, but so far the exercise of copper is still dominated by fire exercise, H65 brass wire|H62 brass capillary|H59 brass row|QSn6.5-0.1 tin bronze bar|imported tin bronze tube|tin bronze plate whose output accounts for about 85% of total international copper production. 1) fire exercise is generally the first few percent of copper or a few thousandths of the original ore, through the The copper concentrate is raised to 20-30% in a closed blast furnace, reflection furnace, electric furnace or flash furnace for matte smelting, the output of molten matte (ice copper) is then sent to the converter for blowing into crude copper, and then in another reflection furnace through oxidation refining and dehybridization, or cast into anode plates for electrolysis to obtain electrolytic copper with a grade of up to 99.9%. The process is simple, adaptable, copper recovery rate of up to 95%, H59 brass row price quotes, but because the sulfur in the ore in the matte making and blowing two stages as sulfur dioxide exhaust gas, not easy to recover, easy to cause pollution.

In recent years, such as silver method, Noranda method and other molten pool smelting, as well as Japan’s Mitsubishi method, fire method exercise gradually to continuous, automated. 2) modern wet exercise with sulfation roasting – leaching – electrowinning, leaching – extraction – electrowinning, bacterial leaching and other methods The method is suitable for low-grade complex ore, oxidized copper ore, copper-containing waste ore heap leaching, tank leaching selected or in situ leaching.

Solid Lubricant Brass Bushing

Bronze Corrosion Resistance, Plain & Self-Lubricating Bearings

Self Lubricating Bearings – Self Lubricating Bronze Bushing.

Bronze is the collective name of all copper alloys except brass and white copper, generally named according to the first main additive element, such as tin bronze, aluminum bronze, silicon bronze, manganese bronze, etc. Compared with brass, bronze has higher strength and corrosion resistance, and in some environments, bronze has worse corrosion resistance than white copper. As corrosion-resistant structural materials, the more practical ones are tin bronze, aluminum bronze and silicon bronze. The corrosion resistance characteristics of each of these three alloys are described below.

1, Tin bronze

There are three kinds of tin bronze commonly used, with tin content of 5%, 8% and 10% respectively, and their corrosion resistance improves with the increase of tin content. Its mechanical properties, wear resistance and castability are better than pure copper, and the corrosion resistance is also higher than copper.

Tin bronze has good corrosion resistance in the atmosphere, the tin bronze surface in the atmosphere to form a dense layer of tin dioxide film, with the increase in tin content, the denser and thicker the tin dioxide film, the better the corrosion resistance. cu-8Sn alloy in the atmosphere corrosion rate of only 0.00015 ~ 0.002mm / year, in fresh water and seawater is also very resistant to corrosion (<0.05mm / year).

It also has good corrosion resistance in dilute non-oxidizing acids as well as salt solutions; however, in nitric acid, hydrochloric acid and ammonia solutions, it is as corrosion resistant as pure copper.

Bronze with a high tin content (8% to 10%) has a high resistance to impact corrosion. Tin bronze is neither prone to stress corrosion rupture nor to decarburization corrosion.

Because tin bronze wear resistance is very good, it is mainly used in the manufacture of pumps, valves, gears, bearings, plugs and other parts that require resistance to wear and corrosion.

2, aluminum bronze

Aluminum content is usually 9% to 10%, and sometimes add Fe, Mn, Ni and other elements. Its casting performance is not as good as tin bronze, but the strength and corrosion resistance are higher than tin bronze.

The high corrosion resistance of aluminum bronze is mainly due to the formation of a dense, firmly adhered copper and aluminum mixed oxide protective film on the surface of the alloy, which has the ability to self-heal after suffering damage. If there are defects such as oxide inclusions on the surface of the alloy, the integrity of the film is damaged and localized corrosion will occur. Therefore, the corrosion resistance of aluminum bronze is related to the manufacturing process.

The corrosion resistance of aluminum bronze is influenced by the composition and organization of the alloy. The corrosion resistance of single-phase a-alloys increases with increasing aluminum content and is best when binary aluminum bronze contains 8-9% aluminum. a+B complex-phase alloys have a higher corrosion rate than single-phase alloys. Co-precipitation composition (11.9 % aluminum) of Cu-Al alloy, its martensite organization than pearlite organization more resistant to seawater corrosion, because the slow cooling due to high aluminum and precipitation of Y2 phase (anode), resulting in a tendency to dealuminum corrosion. When the aluminum content is greater than 11.5%, the tendency of dealumination of Cu-Al alloy increases.

Aluminum bronze is stable in both fresh water and sea water, and is even corrosion resistant in mineral water. It is very stable in high-temperature vapor above 300°C. The mixture of steam and air has no effect on the corrosion of aluminum bronze.

In acidic media, aluminum bronze has high corrosion resistance. It is very resistant to corrosion in sulfuric acid, even at high concentrations (about 75%) and higher temperatures; it also has high corrosion resistance in dilute hydrochloric acid, but is unstable at higher concentrations (20%) or higher temperatures; it is not resistant to corrosion in nitric acid; but is resistant to corrosion in dilute solutions of phosphoric acid, acetic acid, citric acid and other organic acids.

In alkali solutions, because alkali can dissolve the protective film, thus causing serious corrosion of aluminum bronze, aluminum bronze with high aluminum content has a tendency to stress corrosion, mainly due to aluminum bias at grain boundaries, thus causing selective oxidation along the grain boundaries and promoting the destruction of the oxide film under stress. The addition of 0.35% or less of Sn or low-temperature annealing can effectively prevent the tendency to corrosion.

3. Silicon bronze

Commonly used silicon bronze has low silicon (1% ~ 2%) and high silicon (2.5% ~ 3%) two types. The former has similar mechanical properties to 70Cu-30Zn brass and is very easy to cold work deformation, while the corrosion resistance is similar to pure copper; the latter has high strength and better corrosion resistance than pure copper, high silicon bronze often contains 1% Mn silicon bronze’s greatest advantage is that it has good casting and welding properties, and is often used to manufacture tanks and other chemical instruments that work under pressure. Silicon bronze does not spark on impact, so it is particularly suitable for places where there is a risk of explosion.
