合金的一种，A type of alloy that acquires its strength through precipitation-hardening (heat-treatment) and which is used for profiles. Alloys that are not heat-treated acquire their strength through increased additives or cold-rolling and are used primarily for sheeting, strip and foil.
To produce profiles, the smelter plant casts the aluminium alloy to form round ingots whose diameter is adapted to each press, and in lengths of six to seven meters.
Anodizing without adding color. Since the aluminium oxide is transparent, the natural surface is visible.
The distance a pen moves when following the outer contour (outer perimeter) and inner contour (inner perimeter) of a profile. Generally expressed in millimeters. The perimeter constitutes the basis for calculating the surface for surface treatment (perimeter x length).
The power with which the metal is pressed through the tool. Power is now designated in MegaNewtons (MN); formerly tonnes were used. Ten MN is equal to approximately 1,000 tonnes. Sapa’s largest press, P5, develops a maximum power of 65 MN.
Metal produced from aluminium oxide, which in turn is produced from bauxite. In Sweden there is one primary smelter plant, Kubikenborg Aluminium (Kubal) in Sundsvall.
Remelted metal from product or process
A solid profile with a cavity that is almost closed. May also require a hollow die or the redesigning of the profile.
In contrast to a hollow profile, a solid profile has no cavity.
