Bronze Material Grades for Bronze Screws 

Bronze screws and socket head cap screws are manufactured from various bronze alloys, each offering unique properties. Common bronze grades include:

GradeCompositionProperties
C93200 (SAE 660)83% Cu, 7% Sn, 7% Pb, 3% ZnHigh strength, excellent wear resistance, good machinability
C9540085% Cu, 11% Al, 4% FeHigh strength, excellent corrosion resistance, suitable for high-load applications
C8630063% Cu, 25% Zn, 6% Al, 3% Mn, 3% FeHigh strength, excellent wear resistance, ideal for heavy-duty applications
C51000 (Phosphor Bronze)94.8% Cu, 5% Sn, 0.2% PHigh fatigue resistance, excellent electrical conductivity, corrosion resistance

Bronze Socket head cap screws- Manufacturing Process: Forging

Bronze screws and socket head cap screws are typically manufactured using the forging process, which ensures high strength and durability. The steps involved are:

  1. Material Selection: High-quality bronze alloys are selected based on the application requirements.
  2. Heating: The bronze is heated to a specific temperature to make it malleable.
  3. Forging: The heated bronze is shaped into screws using dies and presses.
  4. Machining: The forged screws are machined to achieve precise dimensions and tolerances.
  5. Heat Treatment: Some screws undergo heat treatment to enhance their mechanical properties.
  6. Finishing: The screws are finished with coatings or treatments to improve corrosion resistance and appearance.

Allied Bronze Fasteners

In addition to Bronze screws and socket head cap screws, we offer a wide range of allied bronze fasteners, including:


Standards

Bronze screws and fasteners are manufactured in compliance with international standards to ensure quality and reliability. Key standards include:

StandardDescription
ASTM B283Standard specification for copper and copper-alloy die forgings
DIN 933Metric hexagon head screws with full thread
BS 3692Specification for ISO metric precision hexagon bolts, screws, and nuts
ISO 4762Hexagon socket head cap screws

Finishing Options

Bronze screws and socket head cap screws can be finished with various coatings and treatments to enhance their performance and appearance:

  • Natural Finish: Retains the natural bronze color, suitable for aesthetic applications.
  • Passivation: Improves corrosion resistance by removing free iron from the surface.
  • Electroplating: Adds a protective layer of another metal (e.g., nickel or tin) for enhanced durability.
  • Polishing: Provides a smooth, shiny surface for decorative purposes.

Tolerances

Bronze screws and socket head cap screws are manufactured to precise tolerances to ensure proper fit and function. Common tolerance standards include:

ToleranceDescription
ISO 2768General tolerances for linear and angular dimensions
DIN 267Tolerances for fasteners
ANSI B18.2.1Tolerances for inch-series screws and bolts

Industries Using Bronze Screws
