There are many reasons why metal polishing services are needed for precision metal components. The gleaming finish provides a high-end look to resulting metal components, including those made for home appliances, automobiles, and decorative objects, and many other consumer and industrial applications. The metal polishing process uses abrasion polishing compounds to remove surface imperfections and create a uniform grain preparing the part surface for inspection and surface finishing such as anodize, paint, plating and buffing.
Industries that utilize metal polishing services include, but are not limited to:
- Aerospace and defense
- Commercial and residential cookware or kitchenware

Metal Polishing Benefits & Advantages
Industrial polishing services offer many benefits and advantages for products, such as:
- Corrosion resistance. Metal polishing creates a surface that resists rust and corrosion.
- Aesthetic appeal. Metal polishing restores shine to a previously polished finish or creates a new, improved appearance with a mirror-like gleam.
- Enhanced chemical resistance. Polishing protects the metal from the damaging effects of chemicals.
- Easy to clean. A polished surface prevents adhesion of food, dirt, insects, or other contaminants that can become attached to metal, making it very easy to clean.
- Enhanced efficiency. Since there is no added step of stripping bare metal before polishing, the process is more efficient.
Metal Polishing Capabilities
Helander Metal’s metal polishing services accommodate many types of metals and alloys, including:
- 300 series stainless steel. This metal typically contains at least 10.5% chromium, as well as nickel and molybdenum. 300 series stainless steel is the most commonly used alloy used in stainless steel polishing services. It has a non-magnetic, crystalline structure that has inherent resistance to cracking, etching, and corrosion. It also maintains its strength under high temperatures.
- 400 series stainless steel. 400 stainless steel is a cost-effective stainless steel option when compared to 300 series stainless steel. This magnetic metal typically contains chromium and manganese.
- Carbon steel. Carbon steel is made up of 0.12% to 2% carbon. It is strong, cost-effective, recyclable, and highly durable.
- Aluminum. Aluminum polishing services accommodate many types of aluminum alloys. It is malleable, corrosion resistant, and has a low density. Aluminum is ideal for applications where reduced weight is important.
- Inconel. This high-nickel alloy contains variable quantities of chromium and iron. It is desirable for use in high heat, high-pressure applications.
- Hastelloy. This nickel alloy is known for its high corrosion resistance, chemical resistance, and thermal stability.
- Titanium. While it shares many characteristics with aluminum, titanium has a higher strength-to-weight ratio. Titanium has a higher tensile strength than steel but comes at a higher price.
- Copper. Copper and copper alloys are naturally antimicrobial, corrosion resistant, excellent conductors of heat and electricity, easy to work with, and fully recyclable.
- Bronze. This strong alloy contains tin and copper. It is corrosion, friction, and temperature resistant and is often added to wood or other metals as a decorative accent.
- Brass. Brass is a copper and zinc alloy that adds superior malleability and ductility with lower friction. It is highly sought after for musical instruments, decorative accents, and architecture.
