Alloy 5083-Aluminum Precision Milled Plate
Our concept of precision
Our concept of precision
Precision is – the accurate, precise general measurements such as thickness tolerance, flatness, parallelism and surface roughness, as well as, the focus on the systematic, interior values such as the physical, metallurgical and technological properties. The result is a reproducible maximum internal and external, maximum precision for each plate and each cut.
Aluminium ingots made from especially developed materials based on our experience undergoes a final specific in-house heat treatment. Bypassing the conventional rolling process, our slabs are divided into plates on special saws. The sawing process is so designed that no stresses are induced into the material. The result are plates with extreme low-tension and precision-milled surfaces, very fine-grained, homogeneous micro structure and high strength values.
On stable portal milling machines with more than 2 m wide milling heads we generate precision accuracy and the unique surface characteristic for our Precision Aluminum Plates. Each precision plate is inspected in respect of thickness, flatness, surface roughness and finally PVC- coated for surface protection.
The available range of Precision Aluminum Plates covers all areas of application where precision in combination with higher strength values are required, such as construction of jigs & fixtures, all kind of gauges, all kind of table, indexing and transfer plates, special purpose machines and all parts that justify the term “precision part”.
