Description

Pure aluminium This material is well anodically oxidizable, and possesses 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 the weather proofness are excellent. The material is well suitable for welding and braze welding. Application: apparatus engineering, roll bond, z-bond, household devices, camp and transportation containers for the chemical, pharmaceutical and food industry, roofings, linings, arts and crafts, packing, flow pressed parts (tubes, tube, doses, bottles), reflectors, generally metal-describe, large bottles (to 10 l), metal goods, far neck catches, heat exchanger (profiles, gilled pipes), pressure tanks according to AD-W 6/1, liquid air separation, thermal insulation, antennas, parabolic reflector, tank -, silo trucks, body parts, aircraft construction, tools, forms and devices in mechanical engineering.

Equivalent Materials

This material data has been provided by WIAM,AluKey.

"Typical" values were obtained via a literature search. "Predicted" values were imputed via artificial intelligence technology. While we have placed significant efforts in ensuring data accuracy, "typical" and "predicted" data should be considered indicative and verified by appropriate material testing. Please do contact us if additional information on the the predicted data method is required.
All metrics apply to room temperature unless otherwise stated. SI units used unless otherwise stated.
Equivalent standards are similar to one or more standards provided by the supplier. Some equivalent standards may be stricter whereas others may be outside the bounds of the original standard.
