Machined parts for Bicycle

Boly specializes in making metal components for sport and leisure activities and more particularly for bicycles, mainly road bikes, mountain bikes, hybrid and high-end bikes. Machined from light and strong components, these technical pieces allow a significant weight and performance advantage. Indeed, we respond to all of our customer’s requirements on the matter whether they request a combination of aluminum and carbon for added performance or even the use of titanium components to gain lightness and strength.

Aluminum is most often used for Bicycle components, but others include stainless steel, nickel alloy, titanium, carbon steel, copper, and other certain types of plastic.

Material selectionWhat Specialty Materials Work Best for Bicycle Components?

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

Aluminum Alloys

There is a great deal of aluminum alloys in road bike, mountain bike and folding bike. 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

Stainless Steel and Specialty Steel 

Stainless steel alloys have found increasing usage in Bicycle components that require great strength but can handle the increased weight. The high corrosion resistance found in stainless steel makes it suitable for a range of Bicycle parts, including derailluer, fork, and landing gear components.

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

Carbon Steel

Carbon steel can be found in the structure of the bicycle. Some examples are 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 bicycle.

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

Copper Alloys

With copper’s outstanding conductivity, it is the metal of choice for wiring in most electric bike electrical systems. It is also widely used for precision bearings, bushings, motors and gears.

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