Une variété de matériaux pour répondre à chaque besoin

Material

Emprotec uses different material depending on the technical specifications given by the client and the recommendations of the R&D department. 

 

Soft steel

By using modern laminating techniques it is possible to obtain very thin sheet steel with a clean smooth surface, a regular surface and a range of mechanical characteristics which are compatible with the demands of deep-drawing. This sheet metal is divided into three categories :

  • Sheet metal for standard production
  • Sheet metal for drawing
  • Sheet metal for special drawing

 

Stainless steel

The  excellent mechanical characteristics of stainless steel give it a high degree of formability. The high ratio between mechanical resistance and material weight and the unique characteristics for elongation and strain-hardening make stainless steel suitable for a lot of complex shapes.

 

Brass

The most common are 60/40 and 72/28. This grade (72% copper and 28% zinc) is used for the production on cartridges and sleeves and does not require annealing.

 

Copper

When it is not alloyed with another element red copper has excellent qualities for extra deep-drawing which are often better than those of brass or special steel.

 

Zinc

It is easy to draw, however when deep-drawing complex forms the metal must be heated to between 100°C and 150°C.
