Bright Nickel Silver Strip C7701 C7521 Copper Nickel Zinc Alloy Strip
Copper-Nickel-Zinc alloy, also called nickel silver, German silver, new silver, nickel brass, albata, or electrum, is a copper alloy with nickel and often zinc. Nickel silver is named for its silvery appearance, but it contains no elemental silver unless plated.
Features:
1) Good color
2) High toughness
3) High strength
4) High stability
5) Excellent elasticity with fine silver gloss
6) Good fatigue
7) Rust and corrosion resistance properties
8) C7521 and C7701 have very good deep-drawing performance
Main application:
Copper-nickel-zinc alloy strip is widely used in antenna, cellphone shielding case,crystal resonator shell, silverware, jewelry, glasses, medical apparatus and instruments, zipper and keys’ industry.
