Proprietary Process
Our proprietary degassing and static casting processes eliminate trapped gasses from the molten metal and assure uniform distribution of tin throughout the entire 850 and 852 casting. All metals are alloyed and tested in-house using an optical emission spectrometry (OES) Spectrometer. Optional test bars and chemistry reports are available to meet the customer’s QS and ISO requirements.
Degassing virtually eliminates porosity in the casting.

Natural porosity of molten aluminum before and after degassing.
Most of the tubes produced are rough machined as ordered. Aluminum alloys 850 and 852 can be heat treated to T5 condition.
