DIN 1712-3 Grade 3.0305 H14 – Premium Aluminium for Electrical and Mechanical Applications
Pure aluminium This material is well anodically oxidisable, 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 is high. The forming capacity and the chemical as well as weather proofness are excellent. For welding and braze welding the material is well suitable. Application: Apparatus engineering, roll bond, z-bond, household devices, camp and transportation containers for the chemical, pharmaceutical and food industry, roofing, linings, arts and crafts, packing, flow pressed parts (tubes, tube, doses, bottles).
