What kind of metal is the spot welding machine head?
Chromium copper or tungsten copperPhysical indicators: hardness: >75HRB, conductivity: >75%IACS, softening temperature of 475 DEG C: application of chromium copper resistance welding electrode method of chromium copper through the combination of heat treatment and cold processing to ensure performance, it can obtain the best mechanical properties and physical properties, so used for resistance welding electrode is generally used as the main way. Spot welding electrode or seam welding of low carbon steel, galvanized steel, low carbon steel welding electrode can be used as the grip, shaft and liner material, or large mold, as convex welding fixture, mold steel and heat-resistant stainless steel electrode or embedded. Electric spark electrode: chromium copper has good conductivity and thermal conductivity, high hardness, wear resistance and antiknock. It is used as an electric spark electrode. It has the advantages of good standing, no bending, high finish and so on. Mold base material: chrome copper conductive thermal conductivity, hardness, wear resistance and blast resistance, price ratio of beryllium copper mold material with excellent characteristics, has already begun in the mold industry as a general mold material instead of beryllium copper. Such as soles, molds, plumbing molds, general requirements of high and clean plastic mold, connectors, such as wire, and other products requiring high strength wire. Characteristics: chromium copper has good electrical conductivity, thermal conductivity, high hardness, abrasion resistance, antiknock, crack resistance and softening temperature, high welding speed, low cost, suitable for use as EDM and welding electrodes. Is the preferred material for tungsten and copper based on material cost considerations.
Tell the truth?! The price below normal value belongs to copper plating machine head, the price tends to market price, the head uses brass, the manufacturer that uses red copper can say is very little
Copper, zinc and aluminum alloys with high melting point
