We want to develop and grow with our clients, and deliver high-quality aluminium- and zinc-products for demanding clients.

General of aluminium:

Aluminium (Al) is an interesting metal, which has access to almost unlimited. Advantages of aluminium are for example:

- excellent formability
- low specific gravity
- strength
- appearance (look)
- recyclability

Aluminium in soil solution is 8% but it does not occur in the soil as a clean metal. It occurs in metal oxide, usually bound in clay or stone. In Finland, there is no aluminium production, so all of Finland’s aluminium is imported or recycled.

General of zinc:

Zinc (Zn) is an element, which is brittle and crystalline at a room-temperature. It becames pliable and powdery when heated. Solid zinc is glossy and bluish-white.

Zinc is the fourth most used metal in the world. Zinc is commonly used in pressure casting. Molten zinc is poured into a mold where it solidifies. Die-cast parts are used for example in cars.

Raw materials:

We use the following cast alloys as die-casting raw materials:

AlSi 12 Mg (EN AC-44100)
AlSi 10 Mg (EN AC-43400)
AlSi 9 Mg (EN AC-46000)
Zinc (EN1774)
