Non Poilshed Brass Tubes, Thickness : 10-20mm, 50-60mm, 90-100mm

Copper coil products in various states are mainly used for the production of electrical components, lamp holders, battery caps, buttons,seals, and connectors. Plug-in, mainly used as electrical, thermal, and corrosion resistant equipment. Such as electrical components, switches, gaskets, gaskets, electric vacuum devices, radiators, conductive base materials and automotive water tanks, Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is composed of more than two kinds of elements, a variety of alloys is called special brass. Brass has a strong wear resistance, brass is often used in the manufacture of valves, water pipes, air conditioning inside and outside the machine connection pipe and radiator.

Alloy Grade-:
1. C11000Cu≥99.90
 Material Characteristics  : It has good electrical conductivity, heat conduction, corrosion resistance and processing properties. It can be welded and brazed.The impurities and trace amount of oxygen only have very few effect on electrical and thermal conductivity. But the trace oxygen is easy to cause "hydrogen disease", so it can't be processed and used in high temperature (such as > 370ºC).
Application : Widely used for electric, heat conduction, corrosion resistance equipment. Such as: wire, cable, conductive screw, blastingdetonator, chemical evaporator, storage device and a variety of pipes etc.
2. C10200Cu≥99.97C10300Cu≥99.95
Material Characteristics : High purity, excellent electrical and thermal conductivity, barely no "hydrogen disease", good processing, welding, corrosionresistance and cold resistance performance.
Application :  Mainly used for electrical vacuum instruments, all kinds of hardware products, lamps, pipe fittings, zippers, plaques, nails, springs, sedimentation filters etc.
3. C12000,C12200Cu≥99.90
Material Characteristics : Good welding and cold bending performance. It can be processed and used in reducing atmosphere, but not in oxidizing atmosphere.C12000 has less residual phosphorus than C12200, so its thermal conductivity are higher than C12200.
Application : Mainly used for pipe applications, such as gasoline or gas conveying pipe, drain pipe, condensate pipe, mine pipe, condenser, evaporator, heat exchanger, train parts. It also can be processed to plate, strip, tape and rod.
