ASTM C26000 Common Brass Seamless Tubes, Very Stable For General Corrosion
1. Description
ASTM C26000 seamless brass pipe has very good malleability (the best one among brass) and high strength. It has good machinability and is easy to weld. It is very stable for general corrosion, but easy to produce corrosion cracking. It can be used as thin-walled pipe, corrugated pipe, papermaking net and house building supplies.
The strength of C26000 seamless copper tube is higher than that of ordinary copper tube. Besides good conductivity and thermal conductivity, din-cuzn36 seamless copper tube has high corrosion resistance in atmosphere and fresh water. It is widely used in factories because of its good malleability, easy cold and hot pressure processing, easy welding, forging, tin plating, no tendency of stress corrosion cracking. It is also commonly used in oil pressure system, such as lubrication system, and also widely used in bathroom and shower room water pipe.
