What are stainless steel foils surface finish?
- TR/BA – Bright annealed is a bright cold rolled highly reflective finish. Cold rolled, bright annealed and skin-passed, the product have excellent brightness and good reflexivity like mirror, kitchen apparatus,ornament etc.
- No.4 Finish: The most popular finish for kitchen appliances and work surfaces due to its smooth texture with little reflectivity.
- Mirror Finish: No.8 is a mirror-finished surface with the highest reflectivity without abrasive grains. The stainless steel deep processing industry also calls as 8K plates. Generally, BA materials are used as raw materials for mirror finishing only through grinding and polishing. After mirror finishing, the surface is artistic, so it is mostly used in building entrance decoration and interior decoration.
Features of stainless steel foils
- 1) Strength – Stainless steel is known for its strength in comparison to other metals or alloys. It can stand up against the stresses that cause cracking and breaking in weaker metals. This means that you will be able to enjoy your stainless steel products for a much longer time than if they were made from a lesser quality material.
- 2) Corrosion Resistance – Another benefit of stainless steel is that it resists corrosion from water, chemicals, acidic substances and salt air. This makes it perfect for use in environments where corrosion could quickly ruin regular metal parts or products.
- 3) Durability – Because the material is so strong and resistant to corrosion you will not have to worry about replacing your stainless steel products very often. They will last for years before you need to think about buying new ones. As an added bonus, this helps reduce the cost.

Copper Coils
It may seem that a copper coil is a simple piece of coiled wire that can be wound and put to use. As with any form of industrial product, copper coils have to be precisely engineered to fit an application. The winding process has to be completed with precision to ensure the proper distance between the wires and the diameter of the opening.
Each product that uses copper coils requires that a certain number of turns be made to provide the correct amount of resistance. Inaccurate calculations can lead to inefficiency and possible failure of the coil or device. For this reason, the engineers at Metal Associates guarantee that they have closely examined the specification of an application such that the diameter, spacing, wire thickness, and number of turns exactly matches the design of the product where the copper coil will be used.
