MO40 Alloy Sheet

Low Melting Point Metals
The term “low melting point metals” refers to a group of alloys with a melting point lower than that of tin, typically between 90 to 100°C. These alloy sheets are generally made from metals with relatively low melting points such as tin, bismuth, and lead. The higher carbon content used in MO40 alloy sheets compared to similar products gives them greater strength and durability during heat treatment, but this also results in lower weldability.

These products are commonly used in soldering, safety sprinklers (which automatically activate when the alloy melts), and fuses (which break the electrical circuit when the current exceeds a safe limit).

Applications of MO40 Alloy Sheet

This type of alloy has a wide range of applications, especially in areas requiring higher resistance to wear, hardness, and durability (compared to low-carbon alloys). Common applications include:

• Adapters, arbors, cutters, support blocks, ejectors, support tools, hardware, molds, drill collars, bolts and nuts, mold bases, reamer bodies, and piston rods.

• Also used in rams, hydraulic machine shafts, gears, gear racks, chain rings, spindles, tool bodies, tool holders, connecting rods, chuck bodies, collets, conveyor rods, slides, ejector pins, guide rods, shafts, hydraulic parts, lathe spindles, sawmill components, motor shafts, torsion rods, pinions, pump shafts, motor shafts, nuts, form dies, brake dies, decorative dies, reinforcements, and machinery parts and components.
