Aluminum
Stainless Steel
Mild Steel
Alloy Steel
Brass
Copper
Titanium
Magnesium
Aluminum
(Common Grades: 6061, 7075, 5052, 2024, MIC-6)
Description: Aluminum alloys are lightweight, corrosion-resistant, non-magnetic, and possess excellent thermal and electrical conductivity. They offer a superb strength-to-weight ratio and are generally very easy to machine, allowing for fast production and fine finishes. Different grades offer varying levels of strength, weldability, and corrosion resistance.
Good for:
- Housings and enclosures
- Jigs, fixtures, and tooling
- Automotive and aerospace components
- Heat sinks and thermal management parts
- Manifolds and fluid handling blocks
- Consumer electronics parts

Stainless Steel
(Common Grades: 303, 304, 316/316L, 410, 420, 17-4 PH)
Description: Known for its excellent corrosion resistance, high strength, durability, and hygienic properties. Stainless steels can maintain their properties at high temperatures. While generally harder to machine than aluminum, specific grades (like 303) offer improved machinability. Grades like 316/316L offer superior corrosion resistance, especially against chlorides.
Good for:
- Medical devices and surgical instruments
- Food processing and handling equipment
- Marine hardware and components

Why customers love it: “Its exceptional durability, resistance to corrosion and heat, and clean aesthetic make it ideal for demanding environments and high-quality finished parts.”
Mild Steel
(Common Grades: 1018, 1020, A36)
Description: Mild steel is a cost-effective ferrous material known for its good strength, ductility, weldability, and machinability. It is magnetic and, without protective coating, susceptible to rust. It’s a workhorse material for many structural and general engineering applications.
Good for:
- Structural components and frames
- Jigs, fixtures, and base plates
- Machine parts not requiring high wear or corrosion resistance
- Automotive chassis components
- General fabrication and welding projects

Why customers love it: “It’s the go-to choice for strong, weldable, and highly cost-effective parts when corrosion resistance isn’t the primary concern.”
Alloy Steel
(Common Grades: 4140, 4340, 8620)
Description: Alloy steels contain additional elements (like chromium, nickel, molybdenum) to enhance properties like hardness, strength, toughness, wear resistance, and heat resistance compared to mild steels. Many alloy steels can be heat-treated to achieve very high strength and hardness levels. Machinability varies depending on the grade and condition (e.g., annealed vs. hardened).
Good for:
- Gears, shafts, and axles
- High-strength fasteners and bolts
- Tooling components (molds, dies)
- Automotive powertrain components
- Aerospace structural parts
- Oil and gas industry components
Why customers love it: “When superior strength, toughness, and wear resistance are needed, especially after heat treatment, alloy steels deliver high performance for demanding applications.”
Brass
(Common Grades: C360 (Free-Machining Brass), C260 (Cartridge Brass))
Description: Brass is an alloy of copper and zinc, known for its outstanding machinability (especially C360), good corrosion resistance, excellent electrical conductivity, and attractive gold-like appearance. It’s relatively low friction and non-sparking.
Good for:
- Plumbing fittings and valves
- Electrical connectors and contacts
- Musical instruments
- Decorative hardware and accents
- Gears and bearings (low load)
- Ammunition casings (C260)
- Fast production runs due to high machinability
Why customers love it: “Its unbeatable machinability allows for complex parts to be made quickly and cost-effectively, combined with good aesthetics and corrosion resistance.”
Copper
(Common Grades: C101 (OFHC), C110 (ETP))
Description: Copper is renowned for its exceptional electrical and thermal conductivity, second only to silver. It also has good corrosion resistance and machinability, although it can be ‘gummy’. It is ductile and has a distinctive reddish appearance.
- Good for:
- Electrical contacts, terminals, and connectors
- Heat sinks and heat exchangers
- Busbars and wiring components
- Plumbing components
- Electromagnetic shielding
- Decorative items
Why customers love it: “For applications demanding the highest levels of electrical or thermal conductivity, pure copper is often the best choice, despite its higher cost.”
Titanium
(Common Grades: Grade 2 (Commercially Pure), Grade 5 (Ti-6Al-4V))
Description: Titanium offers an exceptional strength-to-weight ratio, outstanding corrosion resistance (especially in saltwater and chemical environments), and biocompatibility. It maintains its strength at elevated temperatures. However, it is relatively expensive and challenging to machine due to its toughness and tendency to gall.
Good for:
- Aerospace structural components and engine parts
- Medical implants (orthopedic, dental)
- High-performance automotive parts
- Marine hardware exposed to seawater
- Chemical processing equipment
- Sporting goods (e.g., high-end bicycle frames)
Why customers love it: “When maximum strength with minimum weight and superior corrosion resistance are critical, titanium provides unmatched performance, especially in extreme environments.”
Magnesium
(Common Grades: AZ31, AZ91)
Description: Magnesium is the lightest structural metal, offering an excellent strength-to-weight ratio, even better than aluminum. It has good machinability but requires careful handling due to its high flammability risk (chips and dust). It also offers good damping capacity. Corrosion resistance is generally lower than aluminum unless treated.
Good for:
- Applications requiring extreme weight savings (aerospace, automotive race parts)
- Power tool housings
- Electronics enclosures (laptops, cameras)
- Vibration damping components
- Biodegradable medical implants (experimental)
Why customers love it: “For ultimate lightweighting in structural applications, magnesium offers significant advantages over other metals, provided proper machining and handling precautions are taken.”

Description: Nylon is an engineering thermoplastic known for its excellent strength, abrasion resistance, toughness, low coefficient of friction, and good chemical resistance (especially to oils and fuels). It tends to absorb moisture, which can affect dimensional stability and mechanical properties. Additives like Molybdenum Disulfide (MDS) or glass fibers can enhance lubricity/wear or stiffness/strength, respectively.
Good for:
- Gears, bearings, and bushings
- Wear pads and strips
- Rollers and wheels
