Aluminium 1050 sheets used in traffic signs

September 25, 2020

Aluminium 1050 sheets is among the regular aluminum alloys used in traffic sign panels. The temper is H32, which stands for stabilizing aluminium plates to 25% hardness after work hardening. The thickness of traffic sign aluminum alloys is 2/3/4mm, the common specifications are 1200*2400, 1220*2440. Haomei Aluminum produces mainly large plates and does not do post-processing cutting.

Aluminium 1050 sheets used in traffic signs

As the process of urbanization continues to accelerate, there are more and more motor vehicles on the roads, and the traffic pressure on urban roads is gradually increasing. Various traffic signs play a more important role in road safety. The main material is high-quality aluminum alloy. 1050 aluminum sheet is just one of them. 1050 aluminum plate has the characteristics of high plasticity, corrosion resistance, good electrical and thermal conductivity, but its strength is low. It cannot be strengthened by heat treatment, but it can be conventionally welded. In addition to aluminium 1050 sheets, other alloys of aluminum sheets, including 3003, 5005, 5052, 6005 and 6082, are used in traffic panels, too. The advantages of 1050 sheets are low price and simple process.

How to choose suitable aluminum sheets for traffic signs? If the signs will be used in regions of ordinary climates, 1050 alu sheets are enough, but if they will be applied in coastal areas where air corrosion is strong, 5xxx marine grade aluminum sheets are recommended. What’s more, larger suppliers tend to be more reliable than small ones in either product or service.
