As a specially designed fastener, oval copper bolts play a key role in machine building, electrical equipment and electronic engineering.
Oval copper bolts are manufactured from copper alloys and are divided into three main categories:
Pure copper bolts: conductivity ≥ 58MS/m (IACS standard), suitable for high conductivity scenarios
Brass bolts (H62/H65): copper content 62-65%, tensile strength 400-600MPa
Bronze bolts: add tin, aluminum and other elements, wear resistance increased by 40%.
Its unique oval head design has:
Anti-rotation characteristics (contact surface increased by 30%)
Low-profile structure (25% lower height than hexagonal head)
Aesthetically pleasing streamlined shape
Oval copper bolts application areas:
1. Power equipment field
Transformer installation: Utilizing the excellent electrical conductivity of copper (resistivity 1.7 x 10 -8Ω-m)
Switchgear connection: oval head design to avoid tool interference
Grounding system: corrosion resistance 3 times higher than steel bolts
2. Electronics manufacturing industry
Circuit board fixing: to prevent ESD (electrostatic discharge) damage
RF component mounting: low high-frequency loss under skin effect
Heat sink connection: thermal conductivity 386W/(m-K)
3. Special machinery and equipment
Ball mill liner fixing: non-standard customized length up to 500mm
Chemical pipeline sealing: acid and alkali corrosion resistance (pH2-12 range)
Food processing equipment: in line with FDA food safety standards
