We provide professional custom metal and plastic prototyping and manufacturing solutions.

HY Metals is a grouped company providing one-stop service from raw materials to end use products.

We can handle all kinds of materials including Carbon Steel, Stainless steel, Tool steel, Brass, Aluminum, and all kinds of machinable plastic.

Material and Finish for Sheet Metal Parts

For a rough classification, sheet metal materials mainly include Carbon SteelStainless SteelAluminum Alloy and Copper Alloy 4 major categories.

And sheet metal finishes mainly include BrushingPolishingElectroplatingPowder coating , Painting and Anodizing.

Carbon steel is one of the most commonly used materials in sheet metal fabrication. It is much stronger than Aluminum and much cheaper than Stainless steel.

But steel is obviously easy to rust. Then a coating finish will be necessary for steel parts.

Sheet Metal Parts from carbon steel with Zinc plating

Zinc plating,Nickel plating and chrome plating is commonly used on steel sheet metal parts for anti-corrosion purpose. Sometimes the plating also plays a decorative role.

Stainless steel with 2B finish, just keep the raw material finish.

Sometimes to get a cosmetic surface, we will do brushing finish on stainless steel sheet metal parts.

Powder coating is a kind of epoxy resin coating, its thickness always between 0.2-0.6mm,which is much thicker than plating layer.

Powder Coat finish is suit for some outside sheet metal parts which are not sensitive to tolerance and want to get customized colors.

Stainless steel has a better rust resistance ability, widely used in automation equipment, Medical device, kitchen wares and many kinds of outdoor brackets, shells.

Stainless steel parts usually no need any finish, just keep the raw material with 2B finish or Brushed finish.

Aluminum alloy is widely used in aerospace and shells of some equipment to reduce weight and get good rust protection.

At the same time, aluminum alloy also has a very good coloring ability when anodizing.

You can get any beautiful color you want on your aluminum sheet metal parts.

Table 1. Common Material and Finish for sheet metal parts

Sandblasting and anodizing finishes on aluminum extruded tubes.

Sandblast finish can cover the material defects or tooling marks of machined parts. Anodizing can get the anti-corrosion ability and same time get the ideal color for aluminum parts.

So sandblasting+ anodizing is a very perfect finish option for almost all the cosmetic aluminum parts.

Material and Finish for CNC Machined parts

The commonly used materials for CNC machining parts including Steel, Stainless steel, Aluminum, Brass, and all kinds of machinable plastic material.

CNC parts usually required a tight tolerance, so the coating layer is not allowed too thick.

Electroplating for steel and copper parts , anodizing for aluminum parts are the most popular finishes.
