Product Description
C2800 Introduction
Brass is a versatile copper-zinc alloy series with comprehensive mechanical and physical properties, including excellent
electrical and thermal conductivity, structural strength, surface hardness, wear resistance, ductility and outstanding corrosion resistance. Brass materials feature rich and adjustable surface colors ranging from yellow, red, silver to golden tones, which are widely adopted by designers and architects to optimize interior and exterior decorative effects for architectural projects. UNS C28000 (C2800) is a high-quality standard yellow brass alloy within the brass material system. It inherits superior ductility and stable machinability, supporting precision stamping, bending, forging and pressing forming processes. With uniform material texture, bright polishing performance and reliable atmospheric and freshwater corrosion resistance, C2800 brass maintains stable mechanical performance and long service life under conventional working conditions. Widely applied in plumbing pipe fittings,press-fit pipeline components, architectural decorative hardware, instrumentation accessories, valve parts and general mechanical engineering components, UNS C28000 brass serves as a cost-effective and multi-functional alloy for industrial connection and architectural decoration scenarios.

C2800 Brass Hexagon Bolts Introduction
Brass Hexagon Bolt is a high-performance decorative and conductive fastening component made of premium copper-zinc alloy material.Brass alloys feature excellent electrical and thermal conductivity, moderate structural strength, fine hardness, outstanding ductility, wear resistance and superior corrosion resistance, with elegant metallic golden appearance. Adopting precise integral forming and thread rolling technology, this hex bolt delivers accurate thread tolerance, smooth assembly and stable locking performance. Different from carbon steel and stainless steel fasteners, brass hex bolts are non-rusting, magnet-free and oxidation-resistant, maintaining stable performance in humid, atmospheric and lightly corrosive environments. Widely applied in electrical and electronic equipment, architectural decoration, marine engineering, instrumentation, plumbing piping systems, furniture hardware and chemical industry assembly, brass hexagon bolts are ideal fasteners for scenarios requiring conductivity,anti-corrosion performance and high-grade aesthetic appearance.

C2800 Brass Hexagon Bolts Product Processing
1.Raw Material Inspection & Blanking:
Adopt high-quality copper-zinc brass alloy rods that comply with international fastener standards. Strictly inspect alloy composition, surface smoothness, ductility, hardness and internal metallographic structure to exclude oxide inclusions, cracks and material defects. Qualified brass raw materials are precisely cut into fixed-length blanks according to bolt specifications, ensuring consistent size and stable material performance for cold forming.
2.Surface Pretreatment & Cold Heading Forming:
2.Surface Pretreatment & Cold Heading Forming:
Complete professional pretreatment including degreasing, cleaning and surface activation to remove oil stains and oxide layers, improving surface lubricity and forming accuracy. Adopt multi-station cold heading technology to complete one-time integral forming of hex head, transition fillet and bolt rod. The cold forming process maintains continuous metal fiber flow, ensuring dense internal structure, high dimensional accuracy and stable overall fastening strength.
3.Trimming, Straightening & Thread Rolling:
3.Trimming, Straightening & Thread Rolling:
Remove forming burrs and flashes on the hex head and rod surface. Conduct precise straightening treatment to ensure bolt rod verticality and assembly flatness. Adopt high-precision thread rolling process to form standard threads with accurate pitch and complete tooth profile. The rolling molding delivers smooth thread surface and precise tolerance, ensuring flexible assembly, tight meshing and reliable locking performance.
4.Precision Polishing & Surface Finishing:
4.Precision Polishing & Surface Finishing:
Adopt multi-stage fine polishing process to treat the bolt surface, removing tool marks, scratches and oxidation traces. The treatment achieves a smooth, burr-free and bright golden metallic surface, improving texture appearance and surface finish. Polishing also enhances surface compactness and effectively reduces external oxidation and discoloration risks.
5.Anti-Tarnish Treatment & Full Quality Inspection:
5.Anti-Tarnish Treatment & Full Quality Inspection:
Conduct professional cleaning, passivation and anti-oxidation protection treatment to form a dense protective film on the brass surface, preventing discoloration, oxidation and corrosion in atmospheric and humid environments. Carry out full-range quality inspection including dimensional tolerance check, thread precision calibration, surface appearance inspection, hardness test and assembly performance test to ensure all products meet industrial fastening standards.
6.Marking, Packaging & Warehousing:
6.Marking, Packaging & Warehousing:
Mark qualified brass hexagon bolts with specification, standard code and production batch.Complete automatic sorting and counting, and adopt dust-proof, moisture-proof and anti-scratch standardized packaging to protect the polished surface. All finished products are classified and stored in warehouses and delivered after strict final verification.
