- Full mill certificate 3.1 with every delivery
G.AL® C250 is GLEICH's premium cast tool and jig plate, manufactured from EN AW-5083 aluminum alloy (AlMg4.5Mn0.7). We engineer each plate through our proprietary casting process and precise heat treatments to produce a fine-grained, uniform structure with extremely low microporosity and superior dimensional stability.
The result is a plate that stays flat before, during, and after machining. Whether you're milling deep cavities or surface-finishing complex geometries, C250 delivers consistent results across the entire plate - no distortion, no surprises.
These plates offer enhanced anodizing properties, making them perfect for precision machining and visual elements. Its excellent machinability makes it the preferred choice for shops that demand high surface quality and long tool life.
Every G.AL® C250 plate ships with a full EN 10204 3.1 mill certificate, including chemical composition and mechanical property data for complete traceability.

Jigs & Fixtures
G.AL® C250's outstanding stability and surface precision make it ideal for gauges, fixtures, and complex machined parts - often eliminating the need for additional surface work.
Semiconductors & Vacuums
G.AL® C250 offers low outgassing and strong vacuum compatibility. It performs reliably in clean environments, and the corrosion resistance ensures part longevity.
Packaging
Thanks to its anodizing capability, G.AL® C250 is ideal for support plates in packaging equipment where stability is critical and surface performance is a plus.
Automation & Motion Systems
Both rotary indexing tables (up to 2,160 mm in diameter) and coordinate plates can be produced without distortion, thanks to G.AL® C250's flatness and low internal stress.
Mechanical Engineering
Side and back panels, base plates, and precision-machined components can be manufactured quickly and cost-effectively - even when complex details and heavy machining are required.
Model & Mold Making
G.AL® C250 is the go-to material for base and mounting plates in model and mold fabrication, offering excellent flatness, parallelism, and strength.
