Huazhong Welding Materials Co., Ltd specializes in manufacturing copper base solder metal
Copper welding rod refers to the application of copper and copper alloy welding materials, suitable for oxy-acetylene, TIG, MIG welding, widely used in automobile, ship, electrical and other manufacturing industries.
Features of commonly used copper electrode:
T107 is copper electrode, it has good corrosion resistance to air and sea water, mainly welding conductive copper bar, conduit and other copper structural parts.Chemical composition of the deposited metal /% SiMnCu ≤0.5≤0.5≥99
T207 is a silicon bronze electrode.Corrosion resistance to inorganic acid (except nitric acid), organic acid, suitable for copper, silicon bronze and brass welding.Chemical composition of the deposited metal /% SiMnPPBCu 2.5-4.0 < 3.0≤0.30≤ 0.02> 95
T227 is phosphor bronze electrode, has certain strength, plasticity, toughness, wear resistance and corrosion resistance, suitable for welding of copper, brass, phosphor bronze, etc.Chemical composition of the deposited metal /% SnPCU ≤0.50.05-0.3 allowance
T237 is aluminum manganese bronze electrode, excellent wear and corrosion resistance, widely used for welding copper alloy, aluminum bronze, copper and cast iron.Chemical composition of the deposited metal /% SiMnAlCu ≤0.1≤2.07.0-9.0 allowance
T247 high manganese aluminum bronze is copper alloy electrode with core and low hydrogen cover.Excellent wear resistance and corrosion resistance.DC power supply is used, and the electrode is connected to the positive electrode.Application: It is used for welding of high manganese aluminum bronze and other copper alloys, copper alloys and steel, as well as repair welding of cast iron.Such as all kinds of chemical machinery, seawater radiator, valve welding, water pump, cylinder and other surfacing and repair of ship propeller.Chemical composition of cladding metal /% MnFeNiAlCu 9.0-12.02.5-4.01.8-2.55.5-7.5 allowance
T302 Ca Ti coated Cu70Ni30 white copper electrode, can be used in AC and DC, all position welding.Good welding process, weld metal has good plasticity and crack resistance.Application: Mainly used for welding 70-30 copper - nickel alloy.Can also be used for the surfacing of carbon steel parts cladding metal chemical composition of /% MnFeSiPbTi other Cu 1.0-2.50.4-0.75≤0.529-33≤0.02≤0.02≤0.50≤0.5 allowance
Copper base solder series:
A large supply of brass electrode: common grade HS221, belongs to copper and zinc alloy solder, mainly used in gas flame, high frequency, resistance, furnace medium brazing method, brazing copper, copper alloy and steel, cast iron, hard alloy, etc
Large supply of manganese brass welding material, low-price brand HL105, higher strength than the brass electrode, better materials, the shape of silk, and welding piece (20,0.2 0.4 * * 40), melting temperature of 880 degrees to 910 degrees, is commonly used materials, cemented carbide industry has high strength, low cost advantages, is widely used in cutting tools, saw blades, mine drilling tools, such as welding of various kinds of high strength of the products.
We have special strength requirements of phosphorus copper, oxygen free copper, copper solder (welding wire, welding rod, welding ring) without silver wire.
