Top 4 factors about aluminum slug circle price

Aluminum slug circle products are among one of the most widely applied products in semi-processed aluminium industry. The name is a little confusing, for it’s difficult to tell whether it’s an aluminum slug or an aluminum circle sheet. As a matter of fact, it’s an aluminum disc of small diameters. Echoing its extensive application, elements impacting its price are frequently asked about. What influences aluminium circle price? Here we share and elaborate on top 4 factors affecting the price of aluminum discs.

The first is grade. Regular alloy numbers for aluminum slug circles fall on three series: 1xxx, 3xxx and 5xxx. In detail, there are 1050, 1060, 1070, 1100, 3003 and 5052. In particular, 1070 aluminium slugs are applied in tubes for cosmetics, pharmaceutics and domestic articles. 1000 aluminum circles are the cheapest and softest, for they contain the highest share of aluminum metal. 3003 and 5052 are harder and more expensive, used in corrosion resistant products like lamp panels and high pressure cookers.

The second is application. Divided by further process methods, the slug circle group covers spinning and deep drawing aluminum circle sheets. Both kinds of sheets can be processed by cold rolling or hot rolling, with the latter boasting better mechanical properties, especially tensile strength. In practice cold rolled and hot rolled aluminum wafers are used to make cookware, but high-end cookware are usually made of hot rolled wafers. In the same way, alloys featured by better performances are more likely to be used in advanced products.

The third is surface treatment methods. A circle is assumed to be mill finished in the case that no special requirements about surface treatment are from the buyer. In some cases, however, suppliers are required to have aluminum circle discs coated or anodized, which generates pre-painted aluminum circle sheets and anodized aluminum round sheets, the prices of which prove to be much higher because of extra surface process.

The last is aluminum slug circle precision, which incorporates two aspects: the precision of chemical composition and that of specification. The former ensures the purity and quality level of raw materials, keeping waste and recycled aluminium materials out of the door, and guaranteeing basic mechanical properties of an alloy. The latter makes sure that the slug circles are made into given specifications like thickness, temper, surface treatment and diameter, all of which entail accurate control of each processing step from aluminum ingot melting to aluminum circle cutting.

In a word, the top 4 factors influencing aluminum circle price are grade, application, surface treatment methods and precision. Aluminum discs suppliers who have these under control are more likely to offer better products.
