1. Metal Fabrication Overview

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

• Cutting

• Forming

• Bending

• Welding

• Grinding

• Surface finishing

Every stage requires the correct abrasive solution to ensure precision, productivity, and surface quality.

GC Abrasives provides application-engineered abrasive solutions tailored to different metals, processes, and industries.

2. Industrial Classification of Metal Fabrication

Metal fabrication is generally divided into three categories:

2.1 Industrial Fabrication

Used for heavy equipment and process systems such as:

• Pressure vessels

• Storage tanks

• Heat exchangers

• Conveyor systems

• Machine frames

Industrial fabrication requires high-strength cutting and grinding performance, especially on thick steel and alloy materials.

2.2 Structural Fabrication

Used in construction and infrastructure:

• Beams and columns

• Bridges and towers

• Platforms and walkways

• Load-bearing steel structures

This category requires strong weld preparation and edge finishing using durable abrasives.

2.3 Commercial Fabrication

Used in architectural and light industrial applications:

• Stainless steel railings

• Kitchen equipment

• Cabinets and enclosures

• Decorative metalwork

Surface finish quality is critical, requiring fine finishing abrasives.

3. Hard Metals in Fabrication

Hard metals include:

• Stainless steel (304, 316, 310)

• Carbon steel (1018, 4140)

• Tool steel

• Titanium alloys

• Nickel alloys (Inconel)

Stainless Steel

Stainless steel is widely used but prone to heat damage and work hardening.

Recommended GC Abrasives products:

• Ceramic cutting discs

• Ceramic flap discs

✔ Faster cutting
✔ Lower heat
✔ Reduced discoloration

Nickel Alloys (Inconel)

Used in aerospace and energy industries.

Challenges:

• High heat resistance

• Rapid tool wear

• Work hardening

Recommended solutions:

• Ceramic abrasives

• CBN grinding wheels

Titanium

Titanium requires controlled cutting due to low thermal conductivity.

Recommended:

• Ceramic cutting discs

• Low-heat grinding wheels

4. Soft Metals in Fabrication

Soft metals include:

• Aluminum alloys

• Copper

• Brass

• Magnesium

These materials are prone to abrasive loading and surface smearing.

Aluminum

Widely used in automotive and aerospace.

Recommended abrasives:

• Silicon carbide cutting discs

• Silicon carbide grinding wheels

✔ Prevents loading
✔ Clean cutting performance

Copper & Brass

Used in electrical and precision components.

Recommended:

• Silicon carbide abrasives

• Brass wire brushes (non-sparking)

Magnesium

Very lightweight but flammable in dust form — requires controlled grinding conditions.

5. Metal Cutting Processes

Common cutting methods include:

• Mechanical sawing

• Laser cutting

• Plasma cutting

• Abrasive cutting
