Aluminium alloys have high interest to hydrogen. It is very important to remove this gas during melting, which forms as a result of reaction of atmospheric humidity with aluminium, in order to perform quality casting and formation of porosity.

For that purpose, our company is at your service with its nitrogen and chlorine based degassing tablets. Aldegas 100, one of our chlorine based degasssing tablets, performs degassing operation with hexachlorethane it contains, while it also has grain refining feature with boron fluoride effect. Below are the degassing tablets we always keep in our stocks, and you can contact us for detailed information.

Hydrogen dissolves at high rates in molten copper and copper alloys; it decomposes in gas bubbles while solidifying and causes casting failures. CUDEGAS removes not only the gas of liquid metal but also inclusions.

It is used in casting of all copper and copper alloys. CUDEGAS degassing briquettes are in circular form and are dipped in metal bath with a stick. Degassing operation is performed while the temperature is dropping. Agitation gases formed go up to the upper surface of the metal bath.

Minimum 3 minutes are required for degassing in metal amount less than 250 kg. Process time of 5 minutes in metals up to 1000 kg, and 5-10 minutes for amounts over 1000 kg is sufficient.
