Products 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

C28000 Brass Straight Joint Nipple Introduction
The C28000 Brass Straight Joint Nipple is a precision machined hose fitting made of C28000 brass, designed for connecting rubber hoses, plastic tubes and flexible pipelines. It adopts a double barbed structure on both ends with a hexagonal middle section for easy installation and tightening by spanner. C28000 brass provides good ductility, excellent corrosion resistance and outstanding machinability. The barbs firmly bite into the inner wall of the hose to form a stable, leak-free connection for air, water, oil and common low-pressure fluid media. This fitting is widely used in pneumatic systems, water supply equipment, fuel pipelines, garden irrigation and general industrial fluid circuits. It features smooth surface, consistent dimension and long service life under normal working conditions.

C28000 Brass Straight Joint Nipple Product Processing
1.Raw Material Inspection:
The raw material is C28000 brass solid round bar. Upon delivery, we implement strict incoming inspection procedures. Spectrometer testing is performed to verify chemical composition matches C28000 brass specification. Hardness and tensile tests are conducted to confirm mechanical properties meet requirements. We visually inspect the rod surface for cracks, inclusions, pits and deep scratches, and measure diameter, roundness and straightness. Any non-conforming stock will be clearly marked, isolated and returned to the supplier to prevent mixing into production batches.
2.Saw Cutting:
3.CNC Lathe Rough Machining:
4.CNC Finishing & Barb Profile Machining:
5.Ultrasonic Cleaning & Full Inspection:
6.Anti-oxidation Treatment & Final Packaging:
2.Saw Cutting:
Qualified brass rods are fed into a band saw machine to be cut into individual cylindrical blanks, with sufficient machining allowance reserved for subsequent turning processes. Cut end faces are deburred to eliminate sharp edges. Blanks are sorted and stacked on soft storage trays to avoid collision, abrasion and surface damage before machining.
3.CNC Lathe Rough Machining:
The brass blank is securely clamped on the CNC lathe chuck. Rough turning is performed on the outer diameter, central hexagonal clamping section and the barb areas on both ends. Uniform finishing allowance is retained on all functional surfaces. This step removes most excess material, casting skin and major burrs. After rough turning, chips and cutting fluid residues are fully cleared from the workpiece.
4.CNC Finishing & Barb Profile Machining:
The workpiece is repositioned for precision finishing following engineering drawings. The central hexagonal portion is machined to accurate flat dimensions for stable wrench engagement. Dual-end stepped barb profiles are precisely formed, with tight control over barb height, taper angle and spacing, to achieve firm hose grip, anti-pull-off and reliable sealing performance. Fine edge deburring is applied on each barb ridge to avoid cutting the inner wall of rubber or plastic hoses during assembly.
5.Ultrasonic Cleaning & Full Inspection:
Machined nipples are placed in an ultrasonic cleaning tank with alkaline cleaning solution to remove cutting oil, fine brass chips and surface contaminants. Workpieces are rinsed with clean water and thoroughly air-dried in a dust-free zone. 100% inspection is carried out: dimensional check with calipers and micrometers, profile verification of barbs, visual check for burrs, scratches, deformation and surface flaws.
6.Anti-oxidation Treatment & Final Packaging:
Approved parts can undergo passivation treatment optionally to slow brass tarnishing. Parts are packed in batches as customer requirements. Desiccant packets are added inside packaging bags or boxes to isolate moisture and prevent oxidation and discoloration. Each package is labelled with part number, material grade C28000, production batch and inspection mark, then sealed properly for storage and shipment.
