1. Aluminum-silicon welding wire: it is 5% aluminum-silicon alloy welding wire melting point 573-625℃, good fluidity, resistance
Hot cracking ability is strong, but ductility is insufficient. Due to the high silicon content, it is easy to be used in the welding of high magnesium alloy
The formation of brittle Mg2Si in the weld reduces the plasticity and corrosion resistance of the joint. In addition to the weld surface color hair
Dark, after anodizing treatment, the color is different from the base material.A filler material for gas arc welding and gas welding of aluminum alloy parts and castings except aluminum magnesium alloy. oftenUsed for 6061 600 series aluminum alloy, 3000 series and 2000 series aluminum alloy and cast aluminum welding. wide
Widely used in railway locomotive, chemical industry, food and other industries.
2.Aluminum silicon solder wire: lower melting point about 500℃ and higher fluidity (silicon content 12%) than ER4043,
It can also be used as a welding material. Can replace ER4043, higher silicon content, help to reduce thermal cracking and production
Generate higher fillet shear strength.
Commonly used in all kinds of aluminum (thin) parts, condenser, air conditioning tube, high-pressure aluminum tube, automobile water tank, fuel tank, etc
All kinds of difficult welding.
3. Pure aluminum welding wire: pure aluminum welding wire with aluminum content greater than 99.7%, melting point 647-658℃ has a good
The solderability and corrosion resistance of high thermal and electrical conductivity and excellent machining performance, but low strength.
Used as argon arc welding and filling material of pure aluminum, widely used in the connection of aluminum busbar and guide bar in electrolytic aluminum plant
And electric power, chemical, food and other industries.
4. Aluminum and magnesium wire: aluminum and magnesium wire containing nearly 5% magnesium and high manganese content has good corrosion resistance and resistance
Hot cracking, high strength and good malleability. The weld is still white after anodized treatment and can provide good welding joint
For some alloys, the welded joint strength is slightly higher than ER5356
Used as filler metal for aluminum magnesium alloy xenon arc welding, in locomotive carriages, chemical pressure vessels, nuclear industry, manufacture
Applications in ship, refrigeration, boiler and aerospace industries.
