• Artificial aging of steel

• Stress relaxation

• Stress relaxation

Other thermal services:

• Separation of metals by thermal expansion
• Insertion of "Sleeves" by thermal expansion
• Preheating of pieces.
• Various thermal treatments

Remelting of Aluminum:

For the past 10 years we have been working with different processes for remelting of aluminum.

We are able to remelt aluminum ingot, residues and waste of dimensions varying from 1 millimeter to 5 meters in size.

Our remelting service also allows us to recover aluminum frozen inside the melting pot or on other specialized equipment.

With the help of our various types of equipment and our knowledge we are able to remove and recover the aluminum, bath and alumina as well as all other types of contaminants.

Once the process is completed, we return the aluminum to the clients in the form of ingot as well as samples for analyses.

Cleaning and repairing of specialized equipment: :

Over the last years, we have developed a unique expertise for cleaning and repairing of various specialized equipment used in aluminum smelters and by manufacturers.

Here are a few examples:

• Siphons of all sizes
  
• Melting pots
  
• Metal slabs
  
• Metal rods
  
• Steel or cast irons containers
  
• Other equipment upon request
