silicon carbide 80 grit is an ideal choice for the coarse grind in your rock tumbler, boasting an Mohs hardness rating of close to 9.5 on the Mohs scale and only rivaled by diamond and boron carbide grit in terms of hardness.Manufacturers typically shape this abrasive media into an angular grain shape that breaks down regularly to reveal sharp edges.
Sharper and Harder Grains than Aluminum Oxide
Silicon carbide is an extremely robust abrasive, measuring in at 9.1 on the Mohs hardness scale. It works extremely well on rough surfaces and can be used for grinding nonferrous materials, finishing tough and hard materials and filling ceramic parts – as well as rock tumbling and wet sanding!
Selecting the ideal blast media for your job depends on a number of variables, with material considerations playing an especially crucial role. Aluminum oxide is an affordable and flexible choice when it comes to sanding wood, metal and painted surfaces – however it may not be optimal when it comes to handling harder materials like abrasive wheels, slurry or ceramic.
Blast media that contains silicon carbide 80 grit can easily handle hard materials thanks to its sharper and harder abrasive grains, but is less durable than aluminum oxide abrasives due to wear-and-tear issues with their narrow shape and wear-prone qualities. With razor sharp grains perfect for cutting glass, plastic, medium density fiberboard with light pressure but failing to provide smooth sanding on softer materials like wood or soft metal it cannot provide as effective results as its aluminum oxide counterpart.
silicon carbide 80 grit stands out with its distinctive, angular grain shape that breaks down constantly to reveal new sharp edges, making it an excellent choice for applications such as rock tumbling. Reusing black silicon carbide again and again doesn’t cause it to dull down or lose its cutting capability – making it the perfect material to use repeatedly without losing cutting capabilities or becoming dull over time.
More Friable than Aluminum Oxide
Silicon carbide abrasives feature razor-sharp grains that allow it to cut glass, plastic and medium-density fiberboard with very minimal pressure. Unfortunately, though, silicon carbide does not possess the durability of its aluminum oxide counterparts due to being more brittle with narrower particles that wear down more quickly over time.
Aluminum oxide-based abrasives are more durable and have a wider particle size, which extends their useful life. Common coarse through fine grit options exist, which can cut materials with Rockwell “C” scale hardness of 55 or above. Aluminum oxide serves as an economical yet flexible choice that’s great for most sandblasting projects.
Most individuals opt for silicon carbide sandblasting media alongside aluminum oxide abrasives as it produces a more polished surface while still offering aggressive stock removal on metals and woods.
When purchasing abrasives, it is also essential to take Friability Rating into account in addition to Hardness Rating. Friability measures how quickly a media shatters and breaks down after being used – this determines its life before needing replacement. silicon carbide 80 grit offer superior Friability Rating with their ability to be recycled multiple times before replacement is needed; making this more cost-effective choice than products like brown fused aluminum oxide or ruby red alumina which have lower Friability Ratings.
Excellent for Working on Rough Surfaces
silicon carbide 80 grit is an excellent choice for working on rough surfaces due to its hard surface, as it quickly reduces materials. Additionally, it can cut through soft materials like fiberglass, drywall and painted/primed wood without leaving dull spots behind; however it should not be used with metal as this may create dull spots and cause damage – we advise selecting brown fused aluminum oxide instead.
Silicon Carbide is less durable than aluminum oxide due to being more fragile and possessing narrow shapes that wear down quickly. However, it remains an excellent choice for sanding rough materials and polishing surfaces as its razor-sharp grains produce very smooth finishes. While they can easily cut glass, plastic, medium density fiberboard with light pressure pressure; unfortunately they do not perform as effectively with harder metals or woods.
silicon carbide 80 grit can be reused several times when cleaned between uses, provided it is thoroughly rinsed and cleaned between uses. Its porous nature makes it perfect for tumbling gemstones and rocks in a rock tumbler – coarse grits for rough sanding, then finer ones when polished stones are ready to polish! Furthermore, black silicon carbide can also be used for sandblasting, grit blasting and lapping compounds; additionally it’s frequently employed as non slip broadcasting media in concrete floors, sidewalks or plazas!
