Custom Rolled ® ALUMINUM COIL SINCE 1915

United Aluminum's Patented Tougher Spiral Fin Strip Product

Same alloy as you currently use

If your drawings currently specify aluminum alloys such as 1100, 1200, 1050, or 1060 you don’t need to change the specifications. We can apply the Y300® process to any of these alloys – but your fins will be stiffer and more resistant to damage.

No change to the heat-transfer characteristics

We induce the stiffness by changing the grain structure of the metal – the chemical composition is unchanged from your familiar alloy. Therefore the thermal conductivity remains the same so there is no risk when you change to Y300®.

Y300® Aluminum Fin Strip produces tougher, stronger fins!
