Aluminium purchase

We buy all types of aluminium

Aluminium is the scrap metal that we buy most often at RMC Polska Sp. z o.o.. It comes in many forms and series (alloys).

The aluminium has a silvery-white colour that can gently shine.
For everyday items such as kitchenware, packaging or decorative items, appearance and colour will usually be sufficient to identify aluminium.

Aluminium is a lightweight metal. Its low density makes it almost three times lighter than iron. However, the strength of the pure metal is not very high, so other elements must be added.
such as iron, copper, silicon, magnesium, and manganese.
Aluminium alloys with other elements are therefore used. and by suitable heat treatment its mechanical parameters are increased several times.

Aluminium alloys include, among others, casting alloys and alloys used for plastic working. Aluminium alloys are used, among other applications, in aviation, the chemical industry, the automotive industry, the food industry and even in shipbuilding.

Main aluminium grades:

We buy aluminium in every batch and in every form

Casting

This is cast aluminium scrap, which is produced from components cast in foundries. This material must be free of contamination with other metals. Up to 2% of steel impurities are allowed. The size of one piece should be more than 5 cm.

almg purchase

AlMg

5xxx series with a high magnesium content in the alloy. This series is most often used in industry and the construction of aluminium structures. Most often, AlMg is found in the form of aluminium sheet or thick plates.

aluminium purchase

Aluminium radiators

Aluminium radiators mainly come from car demolition. When buying them, we pay attention to moisture and contamination with steel, earth and other substances. The radiators should be free of steel and plastic that are technologically present with them.

Car rim

As the name suggests, this scrap comes from car rims. We buy rims cleaned of weights and steel components (bushings).

Engine heads

This is a group of cast aluminium from automotive engines. This one selected component has a higher purchase price than a standard casting.

Isoprofile

It is a colour profile bonded with PVC plastic. The material comes as post-cushioning or post-manufacturing. It should be cut and cleaned of other metals.

AFL cable

High-voltage cable used in the power industry. The Al. content of such cable ranges from 35% to 80%. The material should be cleaned of clamps, steel elements and other metallic and non-metallic impurities

aluminium procurement

Sector

Aluminium from recycled cables. It is a cable stripped of its insulation. The chemical composition corresponds to the purest aluminium, i.e. the 1xxx series. The sector must not be oxidised, greasy or contaminated with any metals or other substances.

plastic - purchase of aluminium

Plastics

A type of Al consisting mainly of a mixture of series in the form of aluminium sheets, it can be painted or pure. Impurities with other metals up to 2% are allowed in the material. The size of one piece should not exceed 800/800mm.

aluminium procurement

Al line

This aluminium wire is used in the power industry in the construction of low-voltage lines. The line should be cleaned of buckles, steel elements and other metallic and non-metallic impurities.

aluminium purchase

Aluminium scrap

This material comes from the aluminium remelting process in foundries. We buy this material at prices depending on the chemical composition, and the percentage of aluminium in the scale.

aluminium purchase

Profiles

Profiles should be cleaned of other metals and plastics and cut into lengths of up to 1 metre. Profiles are divided into two types, which are detailed below.

Aluminium purchase - price

The price of aluminium depends on its chemical and physical purity
and alloying admixtures. Homogeneous, post-production aluminums with a homogeneous chemical composition are the most expensive.

We can check the price of aluminium on the LME (London Metal Exchange). The price of aluminium at scrap exchange depends on the LME, the euro exchange rate
and the market situation and demand.

Profiles are divided into two types:

  • Clean profile - is most often post-production material and occurs
    in the 6063 or 6082 series (e.g. car sides). A clean profile is an unpainted material. Profile with alloy 6082 has a lower price than alloy 6063.
  • Colour profile - is the same material as a pure profile, but is coated with paint or varnish. It is available as post-production or post-cushioning.

Aluminium - curiosities

The sale of aluminium in foil form began in 1910.
Did you know that for every tonne of aluminium produced from primary raw materials, as much as 12 to 14 tonnes of Co2 (carbon dioxide) are released into the atmosphere?
Aluminium production on an industrial scale began in the early 19th century, but the process of obtaining pure aluminium from its ore (bauxite) was very expensive. Therefore, aluminium was originally considered a precious and valuable metal, and even more valuable than gold and silver.

As such, aluminium was originally considered a precious and valuable metal, and even more valuable than gold
and silver.
Aluminium is resistant to the action of nitric acid, which is able to digest any other metal (excluding precious and rare earths). This is because aluminium forms an oxide layer on its surface, which protects it from the action of nitric acid.
