Copper-plated flat washers, do you know the key knowledge points before choosing [Hardware]

Copper-plated flat washers are a commonly used processing technology in the flat washers series. Before choosing a flat washer, do you know everything about this knowledge? Xiaoshuo will work with you to understand: 1. When choosing gasket materials, you should pay attention to the problem of electrochemical corrosion when different metals are in contact. The material of the flat washer is generally the same as that of the connected parts, usually steel, alloy steel, stainless steel, aluminum alloy, etc. When electrical conductivity is required, copper and copper alloys can be used. 2. The inner diameter of the flat washer should be selected according to the larger value of the thread or screw diameter. The outer diameter of the connected material is soft (such as composite material) or matched with the spring washer. The larger value should be selected. 3. When choosing to place the W washer under the bolt or screw head, in order to avoid interference between the fillet under the head and the washer, a flat washer with an inner hole chamfer can be used. 4. For important bolts with larger diameters, or in order to increase the anti-extrusion ability, steel washers should be used. Steel washers shall be used for the connection of tension bolts or tension-shear composite bolts. Hardware, 15 years of ingenuity and focus on copper-plated flat washers, 20,000+ sets of stamping die customized production experience, monthly processing capacity of 100+ sets of molds, daily production capacity of 3 million punches, stamping accuracy up to 0.01mm, 16 quality inspections strictly for quality check.
