Hot C7441 the white Tongbang B30 copper-nickel alloy with material high-precision C7701 copper-nickel alloy with preferred Berndt Metal Materials Co., Ltd., Dongguan City! 
 The cupronickel based nickel as the main element of the copper-based alloys, was a silver-white metallic luster, hence the name cupronickel. Unlimited solid solution between the copper and nickel, so as to form a continuous solid solution, regardless of how many mutual proportion and constant α - single-phase alloys. When nickel melted into copper D200, when the content exceeds 16%, the resulting alloy color becomes relatively near white, such as silver, nickel, and the higher the content, the more white the color, but, after integration with copper, as long as the nickel content ratio does not exceed 70%, the naked eye will see the yellow copper. Moreover, usually copper-nickel alloy nickel content is generally 25%. All products are ROHS SGS reports and material proof. Good quality, competitive price, welcome new and old customers call to discuss!
