Hard alloy and cast iron join together, use temperature 150 degrees, what glue is better to use?
Why use glue only? Recommend the use of welding, as welding tool is not the same as you can.
High temperature resistant high strength metal and carbide inorganic adhesive YL04-3. For the structure of all kinds of cutting tools such as bonded &def hard alloy cutter and lengthened drill, geological drill; casting airhole crack repair; use temperature of -196 DEG ~800 DEG
Carbide and cast iron are preferred welding methods. Instead of bonding.Can use oxygen acetylene flame gas welding (high combustion temperature, acetylene to hard alloy is heated to a suitable temperature, can be used instead of propane gas), first to the hard alloy is heated to (dark observation) small red, give heating. Were mixed with borax and boric acid as flux, HS201 copper wire dip brazing flux hard alloy and cast iron welding.Bonding shall be considered without welding conditions.The cast iron and carbide surface is polished with fine sandpaper. A soft cloth for wiping dirt and grinding residue. 1:1 AB glue evenly, smear on the contact surface of cast iron and hard alloy. Slightly pressurized. Set aside for 12 hours.
