Materials

As a startup we aren't in the possibility to start with multiple materials and to keep them in stock. We started with the three most common grades of aluminum. However, it's possible to order other types of aluminum, you can request these throug our contact form. 

We will expand to other materials in the near future. Starting with steel and stainless steel.

Physical properties Aluminum

The Density of aluminum and aluminum alloys is roughly 2,6 to 2,8 kg/dm3, this is roughly 1/3 of the density of steel. The low density, and the following weight loss one can achieve is one of the main reasons people love aluminum.
The melting point of aluminum is 660°C and is rougly 3/7 times that of non alloy steel. Aluminum alloys don't have a real melting point, it's more like a melting curve. The curve is dependant on the use of other elements introduced in the alloy. The low melting point is the reason why aluminum is not used in rocket engines.
The linear expansion coefficient of aluminum and aluminum alloys is 23×10-6 tot 24×10-6/K and is thus twice as much as low carbon steel.
The tensile strength of aluminum ranges from 60 to 530 N/mm2, depending on the alloy being used.Taking into account some other physical properties, like a low Young's modulus, one can almost always find a soutable alloy.
The excelent deformability of aluminum makes it the number one choice for extrusion material. Aluminum can be processed in almost any manufacturing process creating a wide choice of aluminum stock like hot-, cold rolled or casted aluminum.
Pure aluminum and copper free alloys are resistant to many environments, explaining the popularity in construction, automotive, chemical, food and other industries. A convincing evidence against atmospheric detoration is the use of aluminum as high voltage conductors and roofing applications. For this a manganeese alloy is used. In marine applications and other light alkaline environments magnesium or manganese magnesium based alloys are in favor. By anodizing, this property can even be improved.
In comparison to a bunch of other metals, aluminum and it's alloys have excellent conductivity properties. For pure aluminum AL 99,5 ca. 36 m/Ω⋅mm2 is obtained. For electrical conductors, pure aluminum or aluminum manganese-silicon alloys are used. The thermal conductivty is also superior and lies between 80 en 230 W/m⋅K for normed materials, depending on the type of alloy.
A vast amount of surface treatments are possible for aluminum and its alloys. This to improve for examble the corrosion resistance or wear. Aluminum is also treated to make a more decorativ appearel. One of the most common surface treatments is annodizing. This method strengthens the natural oxide layer.
