The Ultimate Bronze Cross-Reference Guide: ASTM B505 vs. EN 1982

Simplify your global supply chain with our expert cross-reference chart for bronze and copper casting alloys. Compare ASTM B505 and EN 1982 standards, from Tin Bronzes to Aluminum Bronzes.

You’re looking at an engineering drawing from the United States, and it specifies ASTM B505 C93200 for a critical bearing. Your manufacturing facility is in Europe, and your local supplier has never heard of it. They only work with EN standards and ask if EN 1982 CC493K will do.

Are they the same? Is one a suitable replacement for the other?

This scenario plays out every day in the world of global manufacturing, and a simple mistake can lead to component failure, costly rework, and project delays. Navigating the sea of international material specifications is one of the biggest hurdles for engineers and procurement managers.

This guide is designed to be your definitive Rosetta Stone for cast bronze alloys. We will demystify the two leading standards—America’s ASTM B505 and Europe’s EN 1982—and provide a clear, comprehensive cross-reference chart to make your job easier.

You will learn:

• What ASTM B505 and EN 1982 standards represent.

• The key characteristics of the main bronze alloy families.

• A detailed comparison chart for the most common grades.

Understanding the Standards: ASTM B505 vs. EN 1982

Before diving into the chart, it’s important to know what these standards signify.

• ASTM B505: This is the standard specification from the American Society for Testing and Materials for continuous cast copper alloy bars, tubes, and shapes. Continuous casting is a process that produces a very fine-grained, dense material structure, making it ideal for high-performance bearings and bushings.

• EN 1982: This is the European Norm that specifies copper alloy ingots and castings. The grades are often followed by a “-C” suffix (e.g., CC493K-C), which specifically denotes “Continuously Cast” (Strangguss), making it the direct counterpart to the ASTM B505 process.

While many grades have direct equivalents, some compositions may have slight variations in their minimum or maximum elemental percentages. Always verify with a material test certificate (MTC).

A Quick Guide to the Bronze Families

The term “bronze” covers a wide range of copper-based alloys, each with a unique personality. Here are the main families you’ll encounter in the chart below:

Conclusion: Making the Right Choice

Navigating international material standards doesn’t have to be a source of confusion. By understanding the alloy families and using this cross-reference guide, you can confidently select the correct material for your project, no matter where it’s being manufactured.

The Golden Rule: While this chart provides excellent guidance, always request a material test certificate (MTC or EN 10204 3.1 cert) from your supplier. This document is your ultimate guarantee that the chemical composition and mechanical properties of the alloy you receive meet the exact specifications your design requires.
