Aluminum is a commonly used metal material that is widely used in various industries. We will also come across many aluminum glossary. Do you know what they mean?

Billet

A billet is an aluminium log that is used when extruding the aluminium intoparts and products.

Casthouse products

Casthouse products are all the products we make in the casthouse likeextrusion ingots, sheet ingots, foundry alloys and high-purity aluminium.

Extrusion

The extrusion process starts by heating a billet of aluminium alloy and then forcing it under high pressure through a special steel die using a hydraulic press or ram. Sort of like squeezing toothpaste out of a tube. The result is a piece of aluminium – an extrusion or profile – that will maintain the specific shape of the die and hence has almost unlimited possibilities for design.

Fabrication

After the profile has been extruded it can be fabricated into different shapes and fitted with various features, like holes for screws etc.

Joining

There are a variety of techniques to join aluminum such as fusion welding, friction stir welding, bonding and taping. Features that facilitate easy joining are often incorporated into the design of the extrusions.

Machining

Milling, drilling, cutting, punching and bending are all common methods for shaping aluminium. The energy input during machining is low, meaning a more sustainable final product.

Anodizing

Anodizing is an electrochemical process that converts the surface of aluminium into a long-lasting, high performance aluminium oxide finish. Because it is integrated into the metal rather than just applied to the surface, it cannot peel or chip. This protective finish is very hard and durable and enhances the product’s resistance to corrosion, so it can withstand extreme wear and tear. In fact, the anodized finish is the second hardest substance known to man, exceeded only by the diamond. The metal is also porous, so it can be coloured and sealed, or undergo additional processing, if desired.

There is still a lot to learn about the knowledge and application of aluminum. If you want to know more or have any questions, you can contact us at any time.
