The K100S alloy that delivers flatness, stability, and durability without the weight of steel.
The ATP‑5 plate is forged from a fine‑grained, stress‑free aluminium alloy (K100S) that stays true to its shape from the moment it leaves the mill until it’s fitted into your jig or fixture. Its low density (≈ one‑third the weight of steel) eliminates the need for heavy‑handling equipment, while its inherent corrosion resistance removes the hassle of protective coatings. When you need a perfectly flat, distortion‑free work surface that can be machined to ±0.010 in tolerances, the ATP‑5 is the only logical choice.
| Benefit | What It Means for You |
|---|---|
| Weight Reduction | One‑third the mass of comparable steel plates → faster set‑up, lower shipping costs, and easier manual handling. |
| Dimensional Stability | Fine‑grained, internally stress‑free alloy → < 0.001 in movement during machining. |
| Superior Surface Finish | Factory‑finished to 32 µin (or better) on both faces → ready for high‑precision tooling out of the box. |
| Corrosion‑Free | Naturally resistant to oxidation → no primers, anodizing, or regular maintenance required. |
| High Salvage Value | Aluminium’s market demand keeps resale value strong, outperforming most steel equivalents. |

ATP-5 Cast Tool and Jig Aluminium Plate
More Information
The K100S cast tool and jig aluminium plate is a product that is produced using aluminium alloy that is fine-grained. It doesn’t have any internal stresses. Internally, this grade of aluminium is stable, which ensures that little to no movement is done during machining. This is a machined product that comes with a flat surface. The surface finish is typically 32 micro-inches or better on either side of the product. K100S aluminium can be easily machined without worry of distortion. When proper machining methods are being used, K100S cast aluminium plates are capable of maintaining tolerances that are within the thousandths range. Compared to steel plates, cast aluminium is one-third its weight. Because of this, it removes the requirement for equipment for heavy handling in order to install or set up the product.
Another reason K100S aluminium is widely used is because it is highly corrosion resistant, eliminating the need for protective treatment. Once the tool is no longer needed, the salvage value for this product is a lot more than steels. When strength isn’t a requirement, but flatness and minimal distortion during machining is needed, cast aluminium tools and jig plates can be used. This product isn’t heat treatable. The electrical conductivity of this metal is 36 percent of copper.
Common applications that this product is used for include drill jigs, vacuum chucks, assembly jigs and fixtures, printing machine components, aircraft parts, automotive tools, plastic and rubber molds, CNC routing tables, medical instrumentation, vacuum chambers, electronic parts, templates, hydro press form blocks, prototypes, foundry patterns, circuit printers and food machine components.
