📌 Quick Answer
Emery paper is an abrasive-coated paper or cloth used to smooth, clean, deburr and polish metal surfaces.
Its cutting action comes from emery — a hard natural abrasive made mainly of aluminium oxide (corundum) mixed with iron oxide — bonded to a paper or cloth backing.
🔹 Key Takeaways
- Emery paper = an abrasive-coated paper/cloth for finishing metal.
- Abrasive = emery (aluminium oxide + iron oxide).
- Graded by grit number: low = coarse, high = fine.
- Used for deburring, rust removal, polishing and surface prep.
Introduction
Emery paper, also known as sandpaper, is a popular abrasive material used for smoothing and polishing rough surfaces. It is commonly used in woodworking, metalworking, and automotive refinishing.
Emery paper is a type of sandpaper that is made from abrasive grains of emery, a mineral with a hardness of 8 on the Mohs scale. This abrasive material is used to smooth and shape various surfaces such as wood, metal, or plastic
What is Emery Paper?
Emery paper is a type of sandpaper that is made by gluing fine-grit abrasive particles onto a flexible paper or cloth backing. The abrasive particles are typically made of aluminum oxide, silicon carbide, or garnet, and they come in various grit sizes. The lower the grit number, the coarser the abrasive particles, and the higher the grit number, the finer the abrasive particles.
Types of Emery Paper
There are many types of emery paper available in the market, each with its own unique features and benefits. Some of the common types include:
1. Silicon Carbide Emery Paper – This type of emery paper is best suited for use on metals and hard materials. It is available in grit sizes ranging from 60 to 400.
2. Aluminum Oxide Emery Paper – This type of emery paper is ideal for use on wood, plastic, and soft metals. It is available in grit sizes ranging from 60 to 600.
3. Garnet Emery Paper – This type of emery paper is ideal for use on wood and other soft materials. It is available in grit sizes ranging from 80 to 320.
Types of grades of emery paper:
Emery paper is used in various grades or grits, and the choice of the grade will depend on the type of work that needs to be done.
1. Coarse Grit Emery Paper
Coarse grit emery paper is used for heavy-duty sanding tasks. It has a grit range of 40 to 60 and is used to remove paint, rust, and other rough surfaces from metal or wood. It is also used to level uneven surfaces and prepare them for finer sanding. Coarse grit emery paper can quickly remove material and can be aggressive, so it should be used with care.
2. Medium Grit Emery Paper
Medium-grit emery paper has a grit range of 80 to 120 and is used for sanding surfaces that require a moderate amount of material removal. It is ideal for smoothing rough edges and preparing surfaces for painting or staining. Medium-grit emery paper can also be used to remove minor imperfections from metal surfaces and to prepare surfaces for polishing.
3. Fine Grit Emery Paper
Fine-grit emery paper has a grit range of 150 to 180 and is used for sanding surfaces that require a smooth finish. It is ideal for preparing surfaces for painting or staining and for removing fine scratches from metal surfaces. Fine-grit emery paper can also be used to prepare surfaces for polishing and buffing.
4. Very Fine Grit Emery Paper
Very fine grit emery paper has a grit range of 220 to 400 and is used for sanding surfaces that require an ultra-smooth finish. It is ideal for preparing surfaces for painting or staining and for removing very fine scratches from metal surfaces. Very fine grit emery paper is also used for polishing and buffing.
5. Superfine Grit Emery Paper
Superfine grit emery paper has a grit range of 500 to 1200 and is used for sanding surfaces that require an extremely smooth finish. It is used for polishing and buffing metals and plastics, as well as for finishing wood surfaces. Superfine grit emery paper is also used for preparing surfaces for final coatings or finishes.
Uses of Emery Paper
Emery paper is a versatile abrasive material that can be used for a wide range of applications. Some of the common uses of emery paper include:
1. Woodworking – Emery paper is commonly used in woodworking for sanding and smoothing wood surfaces. It is also used for removing old finishes and preparing surfaces for painting or staining.
2. Metalworking – Emery paper is used in metalworking for grinding and polishing metal surfaces. It is also used for removing rust, paint, and other surface contaminants.
3. Automotive Refinishing – Emery paper is commonly used in automotive refinishing for sanding and smoothing body panels and other surfaces. It is also used for preparing surfaces for painting or clear coating.
Benefits of Emery Paper
There are many benefits of using emery paper for abrasive applications. Some of the key benefits include:
1. Versatility – Emery paper can be used for a wide range of applications, from woodworking to metalworking and automotive refinishing.
2. Consistency – Emery paper provides consistent results, ensuring that surfaces are sanded or polished evenly.
3. Cost-effective – Emery paper is a cost-effective abrasive material, making it an ideal choice for DIYers and professionals alike.
4. Convenience – Emery paper is easy to use and can be cut to size for various applications.

Frequently Asked Questions
What is emery paper?
Emery paper is an abrasive-coated paper or cloth used to smooth, clean and polish metal surfaces by abrasion.
What is emery made of?
Emery is a natural abrasive composed mainly of corundum (aluminium oxide) mixed with iron oxide (magnetite).
How are emery papers graded?
By grit number — a low number means a coarse, fast-cutting grit and a high number means a fine grit for a smooth finish.
What is the difference between emery paper and sandpaper?
Emery paper uses hard emery/aluminium-oxide grit, usually on a cloth backing, and is best for metal; sandpaper uses various abrasives and is commonly used for wood.
