Material: copper-aluminum composite materials; features: through forge welding process, two kinds of materials are welded together, thus combining the advantages of both materials, cutting down the cost and reducing the weight of the operating mechanism. This process is invented by our company and we have got the patent certificate. -Application: applied in high-voltage switching mechanism. -Client Problem: in the past, it was made of only one kind of material by complicated process and had teeth on the outer edge with high cost and low efficiency. -QH Solution: through composite welding of two materials, QH reduces the cost by 60% with no impact on the performance. With the teeth cut, the bearing capacity of the product is up to 5t and the cost for processing the steel teeth can be saved. -Benefits: the cost is reduced by 60%, and with the teeth eliminated, the bearing capacity rises to 5t.
