1. Metal Fabrication Overview

Metal fabrication is the process of converting raw metal stock into finished components through a sequence of operations including:

• Cutting

• Forming

• Bending

• Welding

• Grinding

• Surface finishing

Each stage of fabrication requires the correct abrasive tool to ensure precision, efficiency, and surface quality.

GC Abrasives provides application-driven abrasive solutions tailored to different metals and industrial processes.

2. Hard Metals in Metal Fabrication

Hard metals include high-strength and heat-resistant materials such as:

• Stainless steel (304, 316, 310)

• Carbon steel (1018, 4140)

• Tool steel

• Titanium alloys

• Nickel-based superalloys (Inconel)

• Cobalt-chrome alloys

Stainless Steel

Stainless steel is widely used in food processing, medical equipment, chemical plants, and architectural structures. It is highly sensitive to heat and prone to work hardening.

Recommended GC Abrasives products:

• Ceramic cutting discs

• Ceramic flap discs

These reduce heat buildup, improve cutting efficiency, and minimize discoloration.

Nickel-Based Alloys (Inconel)

Nickel alloys are widely used in aerospace turbines, power generation, and high-temperature environments.

Key challenges:

• Severe work hardening

• High heat generation

• Rapid abrasive wear

Recommended solutions:

• Ceramic alumina abrasives

• CBN grinding wheels for precision grinding

Titanium Alloys

Titanium offers excellent strength-to-weight ratio and corrosion resistance but is difficult to machine due to low thermal conductivity.

Recommended abrasives:

• Ceramic cutting discs

• Controlled grinding wheels for heat management

3. Soft Metals in Fabrication

Soft metals include:

• Aluminum alloys

• Copper

• Brass

• Magnesium

These materials are easier to cut but tend to cause abrasive loading and surface smearing.

Aluminum Alloys

Aluminum is widely used in automotive, aerospace, and construction industries.

Common grades include:

• 6061 (structural applications)

• 7075 (high-strength aerospace applications)

Recommended abrasives:

• Silicon carbide cutting discs

• Silicon carbide grinding wheels

These prevent clogging and ensure clean cutting performance.

Copper & Brass

Copper and brass are widely used in electrical and precision mechanical components.

Recommended abrasives:

• Silicon carbide abrasives

• Non-sparking wire brushes

Magnesium Alloys

Magnesium is extremely lightweight but requires strict safety control due to flammability risks during grinding.
