Garnet is a natural, chemically inert mineral, which fractures into angular, sharp, irregular pieces when under stress. Our garnet, which is mined from a hard rock deposit, is among the hardest in the world with a Mohs rating between 8.0-8.5. Garnet can be found in many different rock types around the world. The chemical composition of garnet varies, resulting in a range of hardness between 6.5 and 8.5 on the Mohs scale, where diamonds, the hardest known natural material, are a 10.
The irregular shape and hardness of garnet, as well as its ability to be recycled, makes it an optimum product for use in the abrasives industry. Garnet is used for water jet cutting, abrasive blasting and water filtration.
Other abrasive blasting materials, such as nickel, copper and coal slag, present health and environmental issues, as they are harmful to humans, animals, plants, trees and water sources. The use of sand for abrasive blasting has declined significantly in recent years due to the risk of silicosis, which is a form of occupational lung disease caused by the inhalation of silica dust.
Garnet, which is a natural and inert mineral, is a safe alternative to sand, slag and other abrasives. It is also heavy and durable which makes it more productive and efficient than other abrasive products.
The Mohawk Garnet deposit is located northeast of Sudbury, Ontario, in the Laurentian Plateau of the Precambrian Shield. The deposit is 14 km long and covers an area in excess of 7500 acres, making it one of the largest assayed garnet deposits in the world.
Mohawk Garnet?s new state of the art facilities ensures that our garnet is clean, washed and uniform in size. Our garnet has a natural hardness of 8.0-8.5 mohs, making it one of the hardest natural garnets currently on the market. Its natural hardness guarantees a superior cutting ability as well as a capacity to be recycled up to six times. Highly recyclable garnet results in less waste and lower freight costs for consumers.
Our garnet is a highly productive and efficient abrasive that cleans at a fast rate, with low dust and consumption rates. The blast profile of our garnet is controlled and even, which reduces the number of required coatings.
Our Garnet Abrasives
Our line of hard rock garnet abrasives includes a wide range of sizes that can be used in air blasting and water jet cutting.
Air Blast Garnet Abrasives
Our hard rock garnet is one of the most durable abrasives available anywhere in the world. Its sharp, angular shape affords you the ability to be aggressive for tough surface preparation applications yet controllable for your less severe requirements. The characteristics of our garnet make it the perfect choice of abrasive for recycling when applicable. We offer a full range of sizes for a wide variety of air blast applications.
16 Mesh Extra Coarse – 4+ mil profile. Heavy mil scale and rust removal.
36 Mesh Coarse – 3.5-4.5 mil profile. Used to remove mil scale, rust and thick coatings.
80 Mesh Fine – 1.5-2.5 mil profile. Used on new steel and aluminium for light rust or thin coatings
16/24 Blend – 3.5-5 mil profile. Used to remove heavy mil scale, rust and thick coatings.
30/40 Blend – 2.5-3.5 mil profile. Heavy coating and rust removal while maintaining profile.
30/60 Blend – 2-3.5 mil profile. New steel and coating removal with consistent profile.
Water Jet Garnet Abrasives
Our hard rock garnet is angular with sharp edges, which makes it the right choice for water jet applications where cutting speed and surface finish are important. The hardness and consistent grain size allows you to maintain high productivity even on the toughest applications.
60 Mesh Hard Rock – Fastest cutting with uniform finish
80 Mesh Hard Rock – Most popular and highly versatile.
120 Mesh Hard Rock – High precision with outstanding edge quality.
