BUMAX® Fasteners: Leading the Way with Superior Corrosion Resistance and Strength

At CSG, we're proud to offer BUMAX® fasteners, renowned for their exceptional performance in demanding environments. Let's delve into the elements that contribute to their outstanding properties: corrosion resistance, tensile strength, and mechanical strength.

Corrosion Resistance

BUMAX® fasteners, with their high molybdenum content, offer exceptional corrosion resistance, making them ideal for harsh environments and critical applications. BUMAX® Ultra, for example, offers corrosion resistance comparable to 316L (A4) stainless steel. These fasteners can withstand exposure to corrosive substances such as saltwater, chemicals, and extreme weather conditions, making them ideal for marine, chemical, and offshore industries.

Tensile Strength

Tensile strength measures how much force a material can withstand before breaking. BUMAX® Ultra boasts tensile strengths exceeding 1,700 MPa, making it the world's strongest bolt. This strength is achieved through strain hardening and precipitation hardening techniques based on Nobel Prize-winning quasi-crystalline precipitate technology. These processes significantly enhance the material's strength while maintaining good ductility.
Mechanical Strength
Mechanical strength includes yield strength, fatigue resistance, and impact resistance. BUMAX® fasteners excel in all these areas, providing reliable performance under dynamic and static loads.
Yield Strength: High yield strength ensures BUMAX® fasteners can withstand substantial loads without permanent deformation, which is essential for continuous or fluctuating forces in aerospace and high-pressure systems.
Fatigue Resistance: BUMAX® Ultra fasteners exhibit excellent fatigue resistance and are suitable for repetitive loading and unloading applications. This property ensures long-term reliability and safety.
Impact Resistance: BUMAX® fasteners are designed to absorb and dissipate energy efficiently, reducing the risk of fracture or failure under sudden shocks or impacts.

Additional Properties
BUMAX® fasteners also stand out due to their:

Magnetic Permeability: BUMAX® products offer low magnetic permeability, making them suitable for applications requiring non-magnetic properties.
High Ductility: Despite their high strength, BUMAX® fasteners maintain excellent ductility, allowing them to deform without breaking under stress.
Resistance to Stress Corrosion Cracking: These fasteners resist stress corrosion cracking, a common failure mode in harsh environments.
Thermal Expansion: BUMAX® fasteners have a coefficient of thermal expansion similar to carbon steel, offering design advantages over austenitic stainless steels.
Customizability: BUMAX® fasteners can be custom-made to meet specific application requirements, ensuring optimal performance for unique challenges.
