Seamless brass tube
Standard: ASTM, DIN, JIS,
Material: copper and zinc alloy ,
Feature: Brass tube is easy to bend, easy to reverse, not easy to crack, not easy to break, has a certain anti frost heave and anti impact ability, so it is used in building water supply system.
Brass has hard texture, is not easy to corrosion and high temperature resistance, high pressure resistance, used in a variety of environments.Such as Electrical brass tube,refrigration brass tube, high pressure resistant brass tube, copper tube corrosion resistance, electric heating tube, industrial copper refrigerant.
Application: Seamless brass tube can be used for heat exchanger and condenser, low temperature pipe, submarine transport pipe,sanitary pipe. Manufacturing sheet material, strip, bar, pipe, casting parts, etc.
