WHAT IS COPPER SLAG?

Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.

(Excerpted from wiseGEEK)

Air-cooled copper slags have a black color and glassy* appearance. As a general rule, the specific gravity will vary with iron content...The unit weight of copper slag is somewhat higher than that of conventional aggregate.

(Excerpted from Publication Number: FHWA-RD-97-148)

* Please note that this glassy appearance results when the slag has been granulated with water. SHARPSHOT® gets its unique qualities by being ambient (air) cooled, and is dull - not glassy.

For ARTICLES on some of the applications for which copper slag is an ideal choice, and for specific details about SHARPSHOT® copper slag, refer to the SHARPSHOT® Technical Data Page in our LIBRARY.

AIR BLASTING ABRASIVES

SHARPSHOT® has been a proven air blasting abrasive for over 25 years. It is an ambient cooled and crushed copper slag abrasive. The cooling and crushing process creates a hard, cubical, and aggressive abrasive.

Shipyards and contractors have relied on SHARPSHOT® for quality and cutting speed at a very competitive price, and it is now the preferred abrasive at many installations.

In tests run for NIOSH by an independent company, SHARPSHOT® was shown to be the best slag abrasive for cutting speed and cost per sq. ft.

SHARPSHOT® is a recycled copper slag abrasive that is environmentally friendly; it is low-dusting, contains very low levels of heavy metals (see MSDS) and is approved to be recycled into the manufacture of Portland cement.

SHARPSHOT® is a low-dusting abrasive containing less than 0.1% free silica.

SHARPSHOT® is available pre-blended with BLASTOX® for jobs involving lead-based paint.

SHARPSHOT® has been approved by CARB (California Air Resources Board) for dry unconfined outdoor abrasive blasting for over 25 years. Our proprietary air-wash system produces the cleanest low-dusting abrasive on the market.

SHARPSHOT® is approved by the U.S. Navy and listed on its qualified products list.

SIZING & APPLICATIONS INFORMATION

SHARPSHOT® 12x30 (Coarse)

SHARPSHOT® 20x50 (Medium)

SHARPSHOT® 30x60 (Fine)

SHARPSHOT® 40x120 (Extra Fine)

SHARPSHOT®

12x30 (Coarse)

Heavy duty size for the removal of layers of old paint and rust from ships, bridges, tanks, etc. This coarse sizing typically - with properly working equipment - produces a 4.5-5.5 mil profile.

SHARPSHOT®

20x50 (Medium)

Medium size for general purpose blasting jobs. This medium sizing typically - with properly working equipment - produces a 3.5-4.0 mil profile. This is also the preferred size for underwater waterjet cutting applications.

SHARPSHOT®

30x60 (Fine)

This fine grade size is often used to clean lightly corroded coatings and new steel. This fine sizing typically - with properly working equipment - produces a profile of less than 2.0 - 3.0 mil.

SHARPSHOT®

40x120 (Extra Fine)

An extra fine grade abrasive for use on carpet, plastic and wood. This product is often used for antique restoration and cars. This fine sizing typically - with properly working equipment - produces a profile of less than 1.5 mil.
