Custom Truck, Auto, Forklift, Bicycles Castings & Forgings

In vehicle manufacturing, cast iron is primarily used in engines, brake systems, and high-load bearing components, relying on its wear resistance and vibration absorption properties to ensure a smooth ride.

·Gray Cast Iron

Gray cast iron is often sand-cast into engine blocks, cylinder heads, brake discs, and exhaust manifolds. Its excellent vibration absorption properties reduce engine noise and ensure dimensional stability.

·Ductile Iron

Ductile iron is sand-cast and heat-treated for crankshafts, control arms, suspension mounts, and differential housings. It offers high strength and impact resistance, meeting the high-load requirements of vehicle chassis.

·Compacted Graphite Iron

Compacted graphite iron offers a balance of strength and toughness and is commonly used in heavy-duty diesel engine blocks and cylinder heads. Temperature-controlled casting achieves a uniform microstructure and improves fatigue resistance.

·Alloy Cast Iron

Alloy cast iron, after alloying and heat treatment, is used in high-temperature, wear-resistant components such as turbine housings, exhaust pipes, and wear bushings, ensuring long-term reliable operation.

Steel is used in vehicle manufacturing for load-bearing, transmission, and safety structures. High-strength, high-precision parts are produced through forging, stamping, welding, heat treatment, and machining. Steel production often incorporates heat treatment processes, such as quenching and tempering or surface hardening, to improve wear resistance and fatigue life, enabling the chassis, suspension, and drivetrain to withstand heavy loads, shock, and prolonged vibration.

· Carbon Steel

Carbon steel is forged and machined into steering knuckles, connecting rods, gears, drive shafts, and crankshafts, offering high strength and impact resistance, meeting the reliability requirements of long-term vehicle operation.

· Low-Alloy Steel

Low-alloy, high-strength steel is stamped and welded into vehicle body rails, cross members, suspension brackets, and bumper beams, reducing vehicle weight and improving collision energy absorption.

· Cast Steel

Cast steel is commonly used in sand casting or precision casting to produce differential cases, steering knuckle brackets, and heavy-duty chassis parts. Subsequent machining ensures assembly precision.

·High Manganese Steel

High manganese steel offers excellent wear resistance and is suitable for track shoes, bushings, and other high-wear parts in tracked vehicles, extending component life.

·Stainless Steel

Stainless steel is used in exhaust systems, mufflers, fuel lines, and fasteners. It offers excellent corrosion resistance and maintains reliability in long-term humid and high-temperature environments.

Aluminum alloys are used in vehicle manufacturing to reduce weight, improve performance, and enhance corrosion resistance. They are commonly manufactured into various parts through die-casting, forging, extrusion, welding, and machining. Aluminum alloys not only achieve lightweighting goals, but also ensure component strength, toughness, and assembly precision through the proper selection of processes and heat treatments. This ensures reliable performance in both everyday driving and extreme conditions for cars, motorcycles, and bicycles.

· Forged Aluminum Alloys

Forged aluminum alloys feature continuous, streamlined fibers, high strength, and excellent toughness. They are used in high-stress components such as suspension control arms, wheels, and steering knuckles in racing and high-performance vehicles, motorcycle frames, and bicycle cranks and hubs, ensuring lightweight yet withstanding impact and fatigue loads.

· Aluminum-Silicon Alloys

Aluminum-silicon alloys are suitable for die-casting engine blocks, transmission housings, clutch housings, oil pans, and motor housings. They offer excellent thermal conductivity and wear resistance, ensuring heat dissipation and stable engine operation.

·Aluminum-magnesium alloys

Aluminum-magnesium alloys have low density and excellent corrosion resistance. They are often extruded and welded into vehicle doors, bumper beams, roof racks, motorcycle fuel tanks, and lightweight subframes, enhancing vehicle strength and extending vehicle life.

·High-strength aluminum alloys

High-strength aluminum alloys undergo solution and aging heat treatments and are machined into suspension arms, steering components, lightweight wheels, and high-stress connectors. They are lighter than steel while still meeting load-bearing requirements.

·Aluminum extrusions

Aluminum extrusions are extruded and machined into electric vehicle battery boxes, radiators, frame structures, and bicycle frames. Anodizing or painting enhances both appearance and corrosion resistance.

Vehicle manufacturing also uses a variety of specialty metals to meet electrical conductivity, wear resistance, and lightweight requirements, as well as specific performance requirements such as high-temperature resistance, corrosion resistance, or wear resistance. These alloys, due to their unique properties, offer exceptional strength, heat resistance, or lightweight properties in demanding applications.

·Magnesium Alloys

Magnesium alloys are extremely lightweight and, through die-casting, can significantly reduce vehicle weight in steering wheel frames, instrument panel brackets, and seat frames.

·Titanium Alloys

Titanium alloys offer high strength and corrosion resistance and are commonly used in high-performance exhaust systems, suspension bolts, and racing components, enhancing durability and performance.

·Copper and Copper Alloys

Copper and copper alloys are used in radiators, water pipes, busbars, connectors, and motor windings. Extrusion and machining ensure efficient electrical and thermal conductivity.

Bronze, with its excellent wear resistance, is used in plain bearings, bushings, and synchronizer rings, ensuring smooth shifting in transmission systems.

Brass is easy to machine and is commonly used in brake line connectors, valve bodies, and electrical terminals, offering ease of assembly and corrosion resistance.
