Heavy Vehicles

We have abundant experience in precision manufacturing parts for construction and mining equipment. We manufacture components for heavy construction vehicles, all heavy vehicles machined parts to match our customers’ exact designs.

Machined parts for Heavy Truck

Machined parts for heavy trucks are an essential component of the vehicle’s construction. These parts are typically made from high-strength metals, such as alloy steel or stainless steel, and are designed to withstand the heavy loads and stresses that are placed on heavy trucks during operation. Boly has abundant experience in precision manufacturing parts for construction and mining equipment. We manufacture components for heavy construction applications include articulated trucks, backhoe loaders, dozers, engines, excavators, generators, motor graders, skid steer loaders and wheel loaders, and more. We supply parts large and small—brackets, electrical housings, interior components, etc.— all custom manufactured to match our customers’ exact designs.

Carbon steel is most often used for heavy truck components, but others include stainless steel, nickel alloy, aluminum, copper, and other certain types of alloys.

Material selectionWhat Specialty Materials Work Best for Heavy Truck Components?

  • Carbon Steel
  • Stainless Steel and Specialty Steel
  • Aluminum Alloys
  • Copper Alloys

Carbon Steel

Carbon steel can be found both in the interior and exterior of the heavy truck. Some examples are clutch housings, suspension parts, control arms, brackets, and the like. Its decorative uses may also range from wheel rims, covers, screws, washers, bolts, nuts, fasteners, and the like. All of these are essential in maintaining the structure and stability of any given heavy truck.

Below are some of the grades in stock:
AISI 1018
AISI 1045
AISI 1144
AISI 1215
AISI 12L14
AISI 4130
AISI 4140
AISI 8620

Stainless Steel and Specialty Steel 

Stainless steel alloys have found increasing usage in heavy truck components that require great strength but can handle the increased weight. The high corrosion and temperature resistances found in stainless steel make it suitable for a range of heavy truck parts, including actuators, fasteners, and landing gear components.

Below are some of the grades in stock:
AISI 303
AISI 304
AISI 316
AISI 630

Aluminum Alloys

There is a great deal of aluminum alloys in heavy truck. Most aluminum alloys offer high weight to strength ratios, corrosion resistance, formability, and favorable pricing.

Below are some of the grades in stock:
Aluminum 2011
Aluminum 4032
Aluminum 6061
Aluminum 6063
Aluminum 7075-T7651

Copper Alloys

With copper’s outstanding conductivity, it is the metal of choice for wiring in most heavy truck electrical systems. It is also widely used for precision bearings, bushings, tube fittings, gears and pumps.

Below are some of the grades in stock:
Copper C3600
Copper C3602
Copper C3604
Copper C4926 (Lead Free)
