Cast Steel Grit Blasting Media, G-80 Grit Size (5 LBS)
Cast steel grit blasting media provides robust cleaning capabilities for steel surfaces and foundry metals. The G-80 grit size is effective at quickly removing contaminants while delivering a relatively aggressive finish. This media can be used in blast cabinets or with portable blasters, making it suitable for workshops that perform rust removal, scale stripping, and surface preparation. Users should monitor media wear and dust control to optimize results.
Cast Steel Grit Blasting Media, G-50 Grit Size (50 LBS)
This product offers a high-volume option for businesses needing longer blasting runs. The G-50 grit size targets efficient material removal with a balance between cutting speed and surface finish. Cast steel grit is softer than aluminum oxide and tends to resist fracturing, making it a dependable choice for repeated cycles on heavy contaminants. It is well-suited to aerospace-related cleaning tasks where mid-range aggressiveness is desirable.
Cast Steel Grit Blasting Media, G-80 Grit Size (25 LBS)
This 25-pound bag of G-80 grit is designed for high-intensity cleaning tasks where rapid metal preparation is required. Cast steel grit delivers a medium etch suitable for subsequent coating adhesion and rust removal. It strikes a balance between aggressive debris removal and preserving base material integrity, making it a solid pick for industrial maintenance and refurbishment projects.
Steel Shot Abrasive Blasting Media, 550 Grit
Steel shot media with 550 grit provides a ready-to-use option for finishing and surface refinement on metal parts. The 550 grit level offers a mid-range finish that can yield a uniform texture while still enabling effective removal of rust, scale, and old coatings. This media is commonly used in blasting cabinets and larger blasting systems for consistent results across multiple parts.
Aluminum Oxide 60 Grit, 14 LBS
Aluminum oxide is a versatile abrasive with a Mohs hardness of 9, suitable for metal and glass work. The 60 grit size is effective for heavy scale removal and surface preparation on stainless steel, aluminum, and wood. This media can be used wet or dry, offering flexibility for various blasting setups, including cabinets and portable rigs. It is lightweight, cost-efficient in larger quantities, and compatible with many blasting tasks.
Aluminum Oxide 12 LBS, 100 GRIT
The 100 grit variant delivers finer finishing and precision cleaning for delicate surfaces. Aluminum oxide at this grit level excels in creating a smooth, even texture and is well-suited for metal finishing tasks and glass etching. Like the 60 grit version, it supports wet or dry operation and is compatible with blasting cabinets and guns for controlled results.
Buying Guide: Key Purchase Considerations
- Material compatibility: Choose media based on the base material (steel, stainless, aluminum, glass) and the desired surface finish. Steel grit and aluminum oxide offer different hardness and fracture profiles that affect aggressiveness and finish quality.
- Grit size and hardness: Coarser grits (e.g., G-50, 60-80) remove coatings faster but roughen surfaces more; finer grits produce smoother finishes with less material removal per pass.
- Volume and cost efficiency: Larger bags deliver lower cost per pound but require appropriate storage and handling. Consider ongoing blasting needs and equipment capacity.
- Wet vs dry operation: Some media are suitable for wet blasting, which can reduce dust and help with coating compatibility. Ensure your system supports the chosen method.
- Durability and lifecycle: Media that resist fracture and wear longer can reduce replacement frequency, especially in high-volume shops. Aluminum oxide is known for longer cycle life in some applications.
- Environmental and safety: Check for free silica concerns and ensure compliant dust management. Recycled or eco-friendly options are increasingly available and may align with workplace safety standards.
- Equipment compatibility: Verify grit size and media type match your blast cabinet or pressure pot, nozzle size, and air supply to avoid excessive wear or clogged passages.
- Finish goals: Define the desired surface texture (rough cleaning, heavy etch, or fine finish) to guide grit choice and blasting parameters.
