High-Conductivity 3.0257 H1x Aluminium Alloy – DIN 1712-3 Standard

Pure aluminium Electrical conductivity alloy according to DIN, ensured by the German electrotechnical commission for electro-technology with, also in accordance to DIN 40 501 part of 1 to part of 4. This material has a very good electrical and good thermal conductivity, however only relatively low mechanical strength. Forming capacity and chemical as well as weather proofness are very good. Application: Roll bond, z-bond, wiring loom-change with particularly high requirements.
