CuSn7
metal· JVASP-122558· CuSn7
CuSn7 is a copper-tin bronze alloy containing approximately 7% tin, a traditional wrought or cast copper-based alloy known for good corrosion resistance and moderate strength. Widely used in marine hardware, pump components, and architectural applications where its combination of workability, durability in seawater environments, and attractive golden appearance make it a practical choice over higher-strength but less corrosion-resistant alternatives.
