The material is super duralumin (A7075 with heat treatment). In recent years, lightweight materials have gained attention for their low specific gravity and strength. Compared to iron and stainless steel, it has less deformation and a specific gravity of about 1/3. Sizes are available in M6, M8, M10, and M12, with the possibility of accommodating sizes other than those listed. Both materials and products are in stock. We also support various surface treatments, including anodizing. Samples can be provided upon request.
