FAQ about our materials

Aluminium is a chemical element with a density of 2.7 g/cm³ and has a silvery colour. It makes up 7.57 % of the earth's crust, making it the most common metal in the earth's crust. This makes aluminium the third most common element in the earth's crust after oxygen and silicon. The aggregate state is solid, but aluminium can be melted at a temperature of 660.32 °C. So far, solid aluminium has been found at around 20 locations on earth in the form of granular to massive aggregates. In general, aluminium is a tough and relatively soft metal, which can be rolled, shaped, pressed, bent and forged due to its ductility. The light metal is usually alloyed and there are many different aluminium alloys.

Aluminum has become an integral part of production in aerospace engineering, vehicle construction, space technology, aircraft construction, electrical and lighting engineering, the packaging industry and many other industries. Here you will find all the semi-finished aluminum products we offer.

The production of aluminum is very energy-intensive, as electrolysis is required to extract it. On the other hand, aluminum is highly recyclable and can be recycled as often as required without any loss of quality.
Here you will find our solution for recycling aluminum and other non-ferrous metals.

The price of aluminum is subject to fluctuations and is not always the same. The global economic situation and the interplay of supply and demand for aluminum are significant factors for the price. Due to its close link with stock market developments, the price of aluminum is subject to daily fluctuations per ton. Aluminum is traded on the London Metal Exchange (LME), where current prices can be viewed. As the largest non-ferrous metal trader, we purchase countless tons of material every year. These large quantities ensure the best possible purchase prices, which we pass on to you in our offers.

Gunmetal refers to a series of copper-based alloys, whereby the name is derived from the copper-red color of the alloy. The possible alloy components include zinc, tin, lead and sometimes nickel, but copper accounts for the largest proportion at 80-90%. Gunmetal is wear-resistant and has good sliding and casting properties as well as resistance to salt water, which is why it is used particularly in shipbuilding. Furthermore, gunmetal is easy to machine, environmentally friendly and free from stress corrosion cracking.

Both materials have their advantages and disadvantages. The positive properties of both materials should therefore be exploited through targeted use in the right areas of application.

Brass is a collective term for a group of alloys, whereby mainly copper and zinc are melted together.
Depending on the area of use and application, other metals can become part of this alloy, for example to adapt technical properties such as strength or similar. Find here our messing range.

We will be happy to process your enquiry for finished parts and find suitable processors from our partner network. We do not carry out the machining ourselves, as we believe that this is the original task of our customers. If you would also like to process parts for us or are looking for a suitable supplier for your drawing parts, please write to us at zeichnungsteile@bikar.com.
