Jig and fixtures are made from a variety of the materials. There are times where the metals are hardened to resist wear and tear. Sometimes, to prevent damage to workpieces, it is made from nylon/fibre
Below is some of the materials used:
Material Description
Mild steel
Contains (<0.3% carbon) . Most suitable for most jigs applications as it is the economical and most widely used material in jigs and fixtures.
Carbon Steel
Contain carbon (0.85%~1.18%). Most suitable for workpieces like woodwork and hand-tools such as files and chisels. It can be hardened to serves as locator and bushings.
High Speed Steel(HSS)
Contains tungsten (18% ~22%) for toughness and cutting strength, chromium (4.3%) for hardening and wear resistance ,vanadium (1%) for retention of hardness at high temperature. Most suitable for cutting tools like drills , reamers and cutters
High Tensile Steel
Contain carbon (0.45% ~ 0.65%) and alloys Ni2Cr1M028 (40%). Most suitable for fasteners as well as high stress like ram press.
Die Steel
Contains carbon (1.5%~2.3)for hardness, high chromium (12%) but alloyed with molybdenum (1%) and vanadium (0.3%~1%) for hardness retention used at high temperatures.Most suitable for forging , casting and extrusion.
Oil Hardening Non-Shrinking Tool Steels
Contain carbon (0.9%~1.1%), tungsten(0.5%~2%) and carbon (0.45%~1%). Most suitable for engraving tools and intricate pressing jigs.
Cast Irons
Contain carbon (2%~2.5%). Most suitable for miling fixture as it can withstand vibrations, machine slides and guide ways.
Nylon & Fibre Most suitable for used in soft lining for lever press/clamps to prevent dent to workpieces under high pressure force
Phosphor Bronze Most suitable in corrosive resistance such as boiler valve
