Product Description:
Copper-Silicon Filler Metals for Brazing, Welding Wires Rod Rings ERCuSi-A
ERCuSi-A filler metals are copper-base alloys containing approximately 3% silicon.
They may also contain small percentages of manganese, tin, or zinc.
The are used for gas tungsten and gas metal arc welding of copper-silicon and copper-zinc base metal, to themselves and also to steel.
When gas metal arc welding with ERCUSi-A filler metals, it generally is best to keep the weld pool small and the interpass temperature below 150°F (65°C) to minimize hot cracking.
The use of narrow weld passes reduces contraction stresses and also permits faster cooling through the hot-short temperature range.
When gas tungsten arc welding with ERCuSi-A filler metals, best results are obtained by keeping the weld pool small.
Preheating is not required. Welding can be done in all positions, but the flat position is preferred.
The main feature of silicon as the main alloy silicon bronze and its use of bronze.
In addition to silicon, industrially applied silicon bronze also contains the main features of less silicon bronze and its main features and uses of manganese, nickel, zinc or other silicon bronze.
Silicon has a limited solid solution in copper. The maximum solubility at 852C is 5.3%, and decreases with decreasing temperature, but the age hardening effect is not strong, and generally no intensive heat treatment is performed.
Silicon can increase the hardness and strength of copper without reducing its processing plasticity, but significantly reduces the conductivity and thermal conductivity of copper.
Silicon bronze has high strength and hardness, good wear resistance, and high elasticity. It is a relatively good elastic material.
Mechanics, corrosion resistance, wear resistance and welding performance, no magnetism, no sparks when impact.
Wear resistance and high temperature strength are high. Its electrical conductivity is also higher than the general high strength copper alloy.
Mainly used to make the main features of various elastic silicon bronze and its use parts and parts working under corrosive conditions and wear parts such as worm gears, worms, gears, village sleeves, brake pins and rods.
The aviation industry is mainly used as the main features of elastic silicon bronze and its use parts and high-strength small structural parts, such as combined airspeed meters, lifting speedometers and altimeter supports, rods, shafts, spring rings and so on.
The strong cold deformation leads to the anisotropy of the elastic properties of the material. Therefore, when it is used as the main feature of the elastic silicon bronze and its use parts, attention should be paid to the direction of the material and the main characteristics of the silicon bronze and its use parts for low temperature annealing.
It is also widely used in the industrial sectors such as machinery, chemicals, petroleum, and ships, and manufactures important parts for the machinery industry and other departments.
