Low Melting Point Alloy As Filler Material For Tube Bending And Profile Tube Forming

Low melting point alloys especially Wood's metal alloy can be widely used as filler materials when bending thin-walled metal elbows into small radii or complex shapes. Resin, asphalt, sand, lead, etc. used in the past are used as filling materials. When these filling materials are used, the inside is easy to move (sand), and it is easy to melt and produce cracks (resin, lead), which will bend the pipe and break it. The low melting point alloy filling material is easy to operate, has a high yield, and is easier to fill. Now this filling material is widely used in the bending pipe of the pressure gauge, the oil pipe of the machine, etc.
