Aluminij Industries offers a wide range of aluminium alloys in the forms of slabs, which are all held up to the European standard EN 573-2:2013 Aluminium and aluminium alloys – Chemical composition and form of wrought products. Slabs are produced by Wagstaff-LHC technology (Low Head Composite Casting Process) by vertical, semi-continuous casting on modern equipment with efficient liquid metal refining units. They are used for rolling into plates, sheets strips, and foil. Casting materials include aluminum and wrought aluminum alloys, with chemical composition stipulated by the international standards, as well as per the customer’s request. Aluminij offers slabs in the form of 1xxx, 3xxx, 5xxx, and 8xxx series.
The most important characteristic of this series is exceptionally high formability, strain hardenable, best corrosion resistance of any alloy group and electrical conductivity.
This series represents commercially pure aluminium, which can range from the baseline 1100 (min. 99.00% Al), to others such as 1050/1350 (min. 99.50% Al) and 1175 (min 99.75% Al).
1xxx series is typically applied in the following processes:
- Electrical conductors;
- Cable sheathing;
- Medical and chemical instrumentation;
- Pharmaceutical containers.
This series is known as manganese alloys where manganese insertions range from 0.5% to 1.8%. 3xxx is of moderate strength, good corrosion resistance and good formability. Alloys from this series are not heat-treatable and are suitable for anodizing and welding.
The base alloys are welded with 1xxx, 4xxx, and 5xxx series filler alloys, depending on their
3xxx series is typically applied for the following:
- Cooking utensils;
- Chemical processing;
- Automative trim;
- Food processing.
This series is known as magnesium alloys where magnesium insertions range from 0.2% to 6.2%. 5xxx series has the highest strength of the non-heat-treatable alloys. It offers good weldability, and as such finds its use in various industries.
These alloys are often welded with filler alloys depending on the magnesium content of the base material and the final application of the product.
5xxx series is typically applied in the following areas:
- Construction of bridges and buildings;
- Pressure vessels.
This series main alloying element is tin, but its content can vary in other elements as well. Iron and nickel are used to increase strength without significant loss in electrical conductivity, and lithium alloys have expectionally high strength and stiffness. It offers a combination of properties that are similar to the 1xxx series, although the way it differentiates is its higher strength, better stiffness and formability.
8xxx series is typically applied in the following:
- Bottlecap production;
- Radiator production;
- Aluminium foil production.
