DIN CuZn36 Common Brass Seamless Tubes For Water Exchanger And Oil Lubricating
Pipe
1. Description
DIN CuZn36 brass seamless pipe has good malleability and high
strength. It has good machinability and is easy to cut and weld. It
is very stable to general corrosion at normal temperature, and the
change of air humidity and temperature has little effect on it. Its
long service life makes it used in many industries. It is the most
widely used common brass variety.
The strength of din-cuzn36 seamless copper tube is higher than that
of copper tube. It has good conductivity and thermal conductivity,
and has high corrosion resistance in atmosphere and fresh water.
And good malleability , easy to hot and cold pressure processing,
easy welding, forging, tin plating, no stress corrosion cracking
tendency. It is usually used in oil pressure system, such as
lubrication system. It is also widely used in bathroom and shower
room.
