DIN 1712-3 Grade 3.0205 F: High-Performance Aluminium Alloy for Engineering Applications

Pure aluminium This material is well anodically oxidizable and has a good electrical and thermal conductivity. The splinter-giving workability is bad because of danger of smearing. Its mechanical strength is low, the plasticity high. The forming capacity and the chemical as well as weather proofness are excellent. The materialist it for welding and braze welding well suitably. Application: Apparatus engineering, roll bond, z-bond, household devices, camp and tansport tanks for the chemical, pharmaceutical and food industry, roofings, linings, arts and crafts, packing, flow pressed parts (tubes, tube, doses, bottles), metal goods, motor vehicle characteristics.
