ER4047 is the eutectic aluminum silicon alloy welding wire with about12% Si element.
Suitable for Al-Si, Al-Si-Mg, Al Si mg Cu wrought aluminium and aluminium (7%Si) argon arc welding. Low melting point and good fluidity.
The tube of solid welding wire is solid, and the tube of flux-cored welding wire has a flux core, which is used to stabilize the arc, improve the operating performance, and play a protective role. Compared with solid wire, flux-cored wire has less spatter, and continuous use will not block the torch nozzle. The performance of flux-cored wire is better than that of solid wire, and the deposition efficiency of flux-cored wire is slightly lower than that of solid wire, but the deposition rate is much faster than that of solid wire.
Bright surface, slight magnetism and no cracks on forming, is widely used in Chemical industry, petroleum, energy, electric power, aerospace, environmental protection, boiler heat exchanger, and bicycle fittings, kitchen and sanitation tools, goods shelf, pet cages, gill racks, decorative handles and baskets, food and medical machinery accesses, etc.
There are many varieties of wire rods. Low-carbon steel wire rods in carbon steel wire rods are commonly called soft wires, and medium and high carbon steel wire rods are commonly called hard wires.
