Product Description
Aluminium Bronze Copper Alloy UNS C61400 Introduction
Aluminium Bronze Copper Alloy UNS C61400 Introduction
C61400 (Aluminium Bronze) is a high-strength, wrought copper-aluminum-iron alloy (CuAl7Fe2) known for excellent corrosion resistance, particularly in seawater and chemical environments. It offers high tensile strength, good ductility, and wear resistance, making it ideal for marine hardware, heat exchangers, fasteners, and pressure vessels

Aluminium Bronze Copper Alloy UNS C61400 Chemical Composition
C61400 aluminum bronze is a high-strength copper alloy primarily composed of copper (approx. 91%), aluminum (6.0-8.0%), and iron (1.5-3.5%), often referred to as CuAI8Fe3. It features excellent corrosion resistance (especially in seawater), high strength, and good wear resistance, making it ideal for marine and industrial applications.

Introduction to common type of C61400 Aluminum Bronze Thread Hex Bolts and Nuts
C61400 Aluminum Bronze thread hex bolts and nuts are high-strength fasteners made from a copper-aluminum alloy, favored for their excellent corrosion resistance, particularly in marine and acidic environments. They are commonly used in high-load, high-pressure, and high-temperature applications, often manufactured through hot or cold forging

Product processing
C61400 Aluminum Bronze thread hex bolts and nuts are manufactured primarily through cold forging or hot forging, followed by machining, threading, and inspection to ensure high corrosion resistance for marine/industrial applications. The process involves raw material preparation, precision heading to form the hex head, thread rolling for strength, and cleaning/heat treatment to achieve required mechanical properties, usually compliant with standards like ASTM F468.
Production Process Steps for C61400 Fasteners
* Material Preparation: C61400 aluminum bronze rods or wires, designed for high strength, are cut to specific lengths.
* Forming (Forging): Cold forging is generally used for smaller sizes to improve grain structure, while hot forging is used for larger,, custom sizes to shape the fastener.
* Hexagon Head Creation: A header machine forms the hexagonal shape at high pressure, providing superior structural integrity compared to machining from solid stock.
* Thread Rolling/Threading: Threads are formed by rolling, which increases fatigue resistance, or by cutting (tapping) for smaller batches.
* Heat Treatment: While C61400 can be used in an as-forged condition, heat treatment may be used to enhance mechanical properties, such as tensile strength.
* Finishing & Coating: Products may be cleaned or coated, such as with PTFE or zinc, to enhance corrosion resistance in seawater environments.
*Quality Inspection: Finished bolts and nuts undergo testing for dimensions, thread fit, and chemical composition (typically6.0-8.0% Aluminum, balance Copper) to meet ASTM F468 standards.
