What is a Patina?
Patina is a brown or a green film found on the surface metals like copper, bronze, and similar metals. It is due to prolonged exposure. Oxidation or different another chemical process produces this tarnish. Get info on copper Patina and Shim Stocks from here.
What are Copper Patina and its formation:
The natural changes that copper metals undergo makes them one of a kind that is hard to replicate. The oxygen interacts with the metal atoms in the presence of water. It forms a copper patina. The higher the temperature, reactions happen at the surface of copper.
Copper furnishings add elegance in a living metal.
Here are different types of Copper Patina

Reasons for choosing Brass Shim Stocks
There are generally 3 factors to consider before using a shim for any project:
Type of material
Why people prefer Brass shims
High malleability: Brass is more malleable than bronze and zinc. Brass is easy to cast. Using shims in the machinery industry to fill gaps or to create a level surface is popular. Brass is the best option because it is a soft metal. It has a low melting point.
Corrosion resistant: Brass is corrosion resistant. It is the primary reason for using brass in pipes and tubing. And It has a strong resistance to tarnishing. It is corrosion resistant to water, fuel, oil or alcohol.
High recyclable: Other metals are entirely different from brass as it uses magnets. Brass lacks magnetism. 90% of the brass can is recyclable. Brass is not ferromagnetic. Low friction: Brass has a low friction rate being a soft metal. Brass is a great conductor of heat and electricity. It is harder and stronger than copper. Brass is stronger according to the proportion of copper and zinc content.
Brass has all the suitable properties for the Shim Stocks. It is the best choice of the manufacturing industries. There are around 300 materials to consider for shims, but brass shims are one of the bests to use in the projects.
