DIN CuZn20 Common Brass Seamless Tubes With Great Strength And Good Malleability
1. Description
DIN CuZn20 brass seamless pipe has high strength, good malleability and high corrosion resistance. It can be used as thin-walled pipe, corrugated pipe, papermaking net and house building supplies.
DIN CuZn20 seamless brass tube has many advantages, such as good conductivity and thermal conductivity, high corrosion resistance in the atmosphere and fresh water, good strength, good malleability, easy to cold and hot pressure processing, easy to welding, forging, tin plating and no stress cracking, so it is widely used in various industrial fields. In particular, oil pressure systems, such as lubrication systems, and plumbing for bathrooms and shower rooms.
