Aluminium Billet are produced by a state-of-the-art hot top casting technology for various specifications. These Billets are free from all surface defects like drags, scratch marks, cold shuts etc. In-line degassing and ceramic foam filtration makes the billets free from internal defects like inclusion, cracks, blow holes, porosity etc. resulting in an excellent metallurgical quality. Grain refiner is added to get fine grains and crack free billets. Homogenizing of billets under close temperature control, improves extrudability and mechanical properties of extruded product. Each Billet is identified on one of its faces with Alloy designation and cast number.
