A Few Facts About Wire
Drawn wire is the process of gradually stretching wire of a specific gauge to the size you need. It can involve heat treating, or annealing, and drawing from larger to smaller spools at a consistent speed.
Some interesting, but little known, facts about drawn wire…
1 metre of 9.5mm aluminium rod drawn down to 2mm will be 22.5 metres long.
1 metre of 9.5mm aluminium rod drawn down to 1mm will be 90 metres long.
1 metre of 9.5mm aluminium rod drawn down to 0.15mm will be 4 kilometres long.
To put that into perspective, 1000 metres of 9.5mm wire rod, weighing 191.5 kgs, drawn down to 0.15mm will circumnavigate the globe.
The melting point of pure aluminium is 660.25 degrees centigrade, however when you add other elements to create an alloy some will reduce the temperature by approximately 5 degrees.
On a world-wide average 4 to 5 tonnes of bauxite are needed to produce two tonnes of alumina, from which one tonne of aluminium can be produced.
In Europe, usually the average bauxite consumption is 4.1 tonnes per tonne of aluminium.
