Aluminium Extrusion
General Information
Simmal Aluminium Ltd is one of the UK's leading suppliers of aluminium extrusion solutions and examples of our downstream products showcased throughout the site are visible in every market sector, from consumer goods to engineering. We will also aim to highlight the benefits of aluminium extrusion and its significance to the global economy. Aluminium is the most abundant metal in the earths crust, (although aluminium does not occur uncombined,) and as such is a dependable and sustainable material and therefore a sensible choice in product specification. This is encouraging as international aluminium consumption has grown steadily in the past several years.
There are many factors that impact on designing with aluminium extrusions. The following pages are intended to help you understand the process of working with aluminium components, from the discovery of it's source ore to its current uses in modern day components. We also provide a number of illustrations which will guide you in the right direction when designing your components. These are intended to inspire you with the immense flexibility aluminium in its extruded form can afford.
Please contact us to discuss your specific needs in detail, you are the next generation of users, and our response will mirror the importance we place on your enquiry.
Quick Facts
- 4 tonnes of Bauxite needed to obtain 1 tonne of Aluminium
- Hall & Haroult quite separately in US & France respectively first extracted Aluminium in 19th Century (1886), using the molten electrolytic process.
- Specific Gravity of Aluminium (SG) = 2.71
- Coefficient of Linear Expansion = 24 x 10:6/ C
