C27200 Copper Alloy
Features Of C27200 Copper Alloy
Outstanding Cold Formability: 98% Yield Rates. Deep drawing, spinning.
Large Strength-Toughness Ratio: 65% shrinking during stretching after heat treatment, with strength increased by 150% during cold working
Improved Resistance to Corrosion: Corrosion over time periods is protected against by surface degradation, resistant to fresh water on the surface, and maintains corrosion passivation
Affordable & Environmentally Friendly: Zinc content reduction, 35% and lead content less than or equal to 0.05% which is expensive.
Crown Universal Decorative: High value, Yellow pure tin classic, Easily fashioned to various surface finishes by various methods.
