Product Introduction

Henan Gnee New Material Co., Ltd. is one of the most professional manufacturers and suppliers of c71640 copper tube in China, specialized in providing high quality copper products with competitive price. Welcome to buy discount c71640 copper tube for sale here from our factory. Customized orders are welcome.

 

The performance advantage of C71640 copper water pipe lies in its high corrosion resistance and good mechanical properties, which maintain high strength and plasticity even at high and low temperatures. In clean seawater, the alloy accepts water flow velocity up to 2.2-2.5%/s, and the highest velocity that can be accepted in slightly saline solution can be up to 4m/s. The alloy can avoid stress corrosion cracking and nickel stripping at high temperature point, so the alloy has good corrosion resistance to clean or have Monel K500 copper-nickel alloy flanges with a certain degree of pollution of seawater and river and bay water.
