CuSn
metal· CuSn
CuSn is a copper-tin alloy, commonly known as bronze, that represents one of the oldest engineered metal systems with applications spanning thousands of years to modern industry. Bronze alloys are valued for their combination of strength, corrosion resistance, and damping properties, making them suitable for applications requiring durability in harsh environments and precise mechanical performance. The exact composition of this CuSn variant determines its specific characteristics; typical copper-tin ratios are used in bearing applications, marine hardware, and architectural components where superior corrosion resistance and fatigue performance outweigh the higher cost versus plain carbon steel.

Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
