Beryllium copper (BeCu), also known as copper beryllium, is a high-performance copper alloy that delivers steel-like strength combined with excellent electrical and thermal conductivity. Containing between 0.5% and 3% beryllium, this premium engineering alloy fills the gap where other copper alloys fail under extreme mechanical stress.

Key Material Properties

• Exceptional Tensile Strength: Reaches tensile strengths up to 1400 MPa after heat treatment, rivaling high-strength alloy steels.
• High Conductivity: Maintains excellent electrical and thermal conductivity compared to steels and superalloys.
• Non-Sparking and Non-Magnetic: Safe for use in explosive environments and delicate electronics sensitive to magnetic fields.
• Wear and Fatigue Resistance: Exhibits superb resistance to galling, continuous flexing, and cyclic stress.
• Extreme Temperature Stability: Retains its mechanical properties in cryogenic temperatures as well as elevated operating environments.

Common Industry Applications

• Oil & Gas: Machined into non-sparking hand tools, drilling components, and housing units for directional drilling equipment.
• Electronics & Aerospace: Formed into heavy-duty electrical contacts, springs, connectors, and switch components for aircraft and satellites.
• Automotive Resistance Welding: Utilized as plunger tips and welding electrodes due to its thermal dissipation and durability.
• Injection Moulding: Selected for core pins and cavities in plastic moulds because it cools rapidly, shrinking cycle times.

We can offer a range of non-threaded fasteners in Beryllium Copper, such as, Circlips, E-Clips, Disc Springs (Belleville Washers), Cotter Pins, Wave Washers and more.

Nimonic 90 is a nickel-chromium-cobalt-based superalloy designed to withstand extreme environments. It maintains exceptional structural integrity and mechanical properties at temperatures where standard steels would instantly soften or warp. Strengthened by additions of titanium and aluminium, this precipitation-hardenable alloy is a staple choice for high-stress, high-temperature engineering.

Key Material Properties

• Exceptional High-Temperature Strength: Retains its mechanical workload capacity at temperatures up to 920°C (1688°F).
• Creep Resistance: Resists permanent deformation under continuous high-stress loads over long periods.
• High-Temperature Oxidation Resistance: Formulated to withstand severe scaling and corrosion in hot gas environments.
• Fatigue Endurance: Endures rapid, repeated thermal cycles and mechanical vibrations without cracking.

Common Industry Applications

• Aerospace & Aviation: Fabricated into gas turbine blades, discs, rings, and hot-section structural components.
• Automotive Performance: Used to manufacture high-performance turbocharger rotors and exhaust valves for racing engines.
• Industrial Gas Turbines: Chosen for high-temperature springs, fasteners, and shroud segments in power generation plants.
• Nuclear Engineering: Applied in high-temperature reactor core components due to its stability under thermal stress.

Titanium non-threaded fasteners are the ultimate choice for critical engineering projects because they offer an unmatched combination of high strength, extremely low weight, and absolute corrosion resistance. Choosing titanium over traditional metals like steel or aluminium ensures that your assemblies can withstand extreme environments without adding unneeded weight.

It offers corrosion resistance in elements such as salt-water (subsea conditions) and other harsh environments. It is also up to 45% lighter than normal steel, but is denser than aluminum.

Why Engineers choose Titanium Non-Threaded Fasteners.

Exceptional Strength-to-Weight Ratio: Titanium is roughly 45% lighter than steel while delivering equal or higher tensile strength.
Immunity to Rust: It naturally forms a stable, protective titanium oxide film. This makes it impervious to saltwater, chlorides, and harsh industrial chemicals.
Thermal Stability: These fasteners maintain their structural integrity across massive temperature spikes, performing reliably from cryogenic conditions up to 400°C.
Non-Magnetic Properties: Highly useful for preventing electronic or magnetic interference in sensitive instruments.

Phosphor bronze is a copper alloy containing copper, tin, and phosphorus. The addition of tin increases corrosion resistance and strength. Phosphorus increases wear resistance and stiffness. This combination creates a highly durable material widely used in demanding electrical, marine, and industrial applications.

Key Material Properties

• High Elasticity: Retains its shape perfectly after repeated bending or flexing.
• Fatigue Resistance: Resists cracking or breaking under continuous mechanical stress.
• Low Friction: Provides excellent wear resistance when rubbing against other metals.
• Corrosion Resistance: Withstands harsh environments, including saltwater and chemicals.
• Electrical Conductivity: Conducts electricity efficiently while maintaining structural strength.

Common Industry Applications

• Electronics: Used for electrical springs, switches, relays, and connectors due to its conductivity and spring retention.
• Marine Engineering: Formed into ship propellers, shafts, and underwater bolts because it resists saltwater corrosion.
• Musical Instruments: Selected for acoustic guitar strings, saxophone bells, and cymbals to produce a bright, rich tone.
• Heavy Machinery: Machined into sleeve bushings, thrust washers, and gears requiring high load-bearing capacity.

Popular Material Grades

• Grade C51000 (5% Tin): The most common grade for electrical contacts, terminals, and springs.
• Grade C54400 (4% Tin, 4% Lead, 4% Zinc): Extremely easy to machine, making it ideal for bearings, bushings, and gear parts.

A4 (AISI 316) grade stainless steel is a highly corrosive stainless steel that contains molybdenum. It has a higher Nickel content to that of A2 stainless steel.

A2 Stainless = 18/8 Stainless (18% chromium, 8% nickel)

A4 Stainless = 18/10 Stainless (18% chromium, 10% nickel)

Here are some key features of A4 Stainless Steel:

• This grade contains anti-corrosive properties making a great choice for marine applications.
• The molybdenum content within this stainless, increases the corrosion resistance to withstand attack from industrial chemicals, chlorides and solvents.
• This grade of stainless is also used in surgical environments, as it’s smooth surface and anti-corrosive properties makes it easy to clean.
• A4 Stainless has long durability.

Here at Caleb Components, we can offer a wide range of our non-threaded fasteners in A4 Stainless Steel, including Circlips, E-Clips, Spring Tension Pins (Roll Pins) and Cotter Pins.
