Available materials

Alloy Steel 4140

The increased levels of carbon in this material cause it to be stronger and better-enforced than regular steel. It is a good option for bolts, pressure systems, and projects with hardening requirements. It also has good corrosion resistance.

Alloy Steel 4340

Steel 4340 is a material with excellent strength properties and toughness. At high temperatures, it maintains its structure and durability. Some example applications include shafts, mechanical gears, levers, and operational parts.

Mild Steel 1018

This material option is easily welded and well suited to surface-hardening processes. Once hardened, mild steel 1018 is extremely versatile, easy to machine, and is best used for projects ranging from gears to molds.

Mild Steel 1045

Steel 1045 has a high tensile strength, is cost-effective, and is impact resistant. It can be hardened through heat treatment or induction. It can also be welded and machined if prepared properly. Some common uses are pins and ratchets.

Mild Steel A36

This type of steel is very common and easy to come by. It also has excellent welding properties and can be used in a variety of applications. One of the most common uses for Mild Steel A36 is structural supports.

Tool Steel O1

A strong material option that provides your project with excellent wear-resistance. It retains edges well, is good for machining purposes, and is great for producing tools like punches, blades and molds.

Tool Steel A2

Tool Steel A2 is an air-hardening material with good wear-resistance and minimal form distortion during heat treatment and hardening. It is a blend of good performance, optimal price, and overall performance.

  • FAQ 2: What CNC processes do you offer?

    We have CNC milling machines and CNC turning lathes.

  • FAQ 3: What types of finishes do you offer for CNC parts?

    We can leave your parts as-machined, or andonize, powder coat, bead blast, or hard coat andonize them. You can specify the finish you want when placing your order.

  • FAQ 4: What CNC material types do you offer?

  • FAQ 5: Do you offer rush production?

    Rush production is available for CNC orders. You can specifiy rush production when placing your order.

  • FAQ 6: What process is CNC considered to be?

    CNC is considered to be a subtractive process, since it works by cutting away at a block of material to form the desired object.

  • FAQ 7: What does CNC stand for?

    CNC means Computer Numerical Control. This refers to the manner in which a computer is programmed with numbers to create the part.
