C19210 Copper Alloy Strip/Foil Description
C19210 Copper Alloy Strip/Foil has good electrical and thermal conductivity, high strength, hardness, high resistance to softening temperature, corrosion resistance, stress corrosion resistance, etc. The strip has high precision, good shape, and no residual stress, and is used in electronic industry connectors and large-scale integrated circuit lead frame materials.
C19210 is a copper alloy, often referred to as a high-copper alloy, which is specifically designed for use in applications requiring high strength, good corrosion resistance, and excellent electrical conductivity. This alloy includes small amounts of iron and phosphorus, which enhance its mechanical properties without significantly compromising its conductivity.
