- Aluminium AlloysAluminium alloys are the light, fast-machining metals of the machine shop; the heat-treatable 6061 and 7075 grades dominate machined parts.Sep 7, 2026
- Carbon & Alloy SteelsCarbon and alloy steels are the everyday machining steels — iron with carbon alone or with chromium, molybdenum and nickel added; how their grades behave.Sep 7, 2026
- Cast IronCast iron is iron with carbon above 2 percent, cast to shape rather than rolled: grey iron machines freely, ductile iron is tough and white iron is ground.Sep 7, 2026
- Copper AlloysCopper alloys run from gummy pure copper to free-cutting brass, the benchmark of machinability: machining brass, bronze and copper, and their alloy families.Sep 7, 2026
- Hardness ScalesHardness scales — Rockwell C and B, Brinell and Vickers — state how hard a metal is; drawings cite them because hardness forecasts how a material machines.Sep 7, 2026
- Heat TreatmentHeat treatment is the controlled heating and cooling of metal that sets its hardness and machinability — the reason one steel grade can be easy or unmachinable.Sep 7, 2026
- MachinabilityMachinability is how easily a material is cut: strength, work-hardening, heat and reactivity make metals hard to machine, and the shop can shift the balance.Sep 7, 2026
- Material ConditionMaterial condition is the state stock arrives in: hot-rolled or cold-drawn, annealed or pre-hardened, T6 aluminium - and it decides the machining.Sep 7, 2026
- Nickel SuperalloysNickel superalloys keep their strength at turbine temperatures, and that strength and severe work-hardening make them among the hardest metals to machine.Sep 7, 2026
- Machining Plastics & CompositesMachining plastics and composites is cutting soft, heat-sensitive material: sharp high-rake tools, controlled heat and gentle workholding for acetal to CFRP.Sep 7, 2026
- Stainless SteelStainless steel is the corrosion-resistant iron-chromium family; its austenitic 300 series work-hardens fast, and that sets every rule of machining it.Sep 7, 2026
- Titanium AlloysTitanium alloys are strong, light and corrosion-resistant, but they hold their heat and gall the tool: how the Ti-6Al-4V, beta and CP grades are machined.Sep 7, 2026
- Tool SteelTool steel is the steel of dies, moulds and tooling: the O1, A2, D2, H13 and P20 grades, and how they are machined soft and hardened for use.Sep 7, 2026
