Materials

Choose Your Keyboard Case Material

The material you choose defines the weight, feel, sound, and durability of your keyboard. 

We machine all of these — so you can pick what fits your vision.

Aluminum

6061-T6 · 6063 · 5052

The most popular choice for premium keyboards. 6063 offers the best surface finish for anodizing. 7075 for extreme rigidity.

  • Lightweight yet rigid
  • Excellent anodizing response
  • Great heat dissipation
  • Best price-to-performance

Stainless Steel

304 · 316L

Heavy, solid, and virtually indestructible. Delivers a unique low-pitch sound signature and unmatched durability.

  • Extreme durability
  • Premium weight (2-3x aluminum)
  • Distinctive sound profile
  • Corrosion-resistant

Brass

C360 · C260

Dense and sonorous. Adds significant weight and delivers a deeper, more resonant typing sound. A favorite for custom builds.

  • Dense — adds 1.5-2kg to a case
  • Deep, satisfying sound
  • Unique gold/patina aesthetic
  • Excellent machinability

Polycarbonate (PC)

translucent

The RGB-friendly choice. Crystal clear or frosted — perfect for showing off underglow and switch lighting.

  • Crystal clear or translucent
  • Lightweight — great for travel
  • Impact-resistant
  • Unique “thocky” sound

Finishing Options for CNC Keyboard Cases

We offer a wide range of decorative finishes tailored for CNC-machined keyboard cases. In addition to our in-house anodizing line, we work with trusted partners specializing in electrophoresis, powder spraying, PVD, clear coating, and laser etching to meet both aesthetic and functional requirements.

Custom Bicycle Components Overview

What Are Bicycle Components?

Bicycle components are the individual parts that work together to create a complete, functional bike. They include frames, handlebars, stems, cranks, pedals, hubs, seat posts, brake parts, drivetrain pieces, and other structural or performance-focused elements. Each component plays a specific role in strength, control, comfort, or power transfer.
 
For custom bicycle projects, component design can influence weight, fit, durability, and riding performance. CNC machining is commonly used for aluminum bicycle components that require accurate dimensions, complex shapes, and consistent finishes, making it suitable for prototypes, premium builds, and small-batch production.

Components of Custom Bicycle Components

Custom bicycle components can include several precision-made parts that influence fit, strength, weight, and riding performance:
 
  • Stems and Handlebar Parts: Connect steering components and support precise rider positioning.
  • Crank and Drivetrain Parts: Transfer pedaling force efficiently through the bicycle.
  • Hubs and Axle Parts: Support smooth wheel rotation and stable alignment.
  • Brake Components: Include mounts, adapters, and other parts used for controlled braking.
  • Frame and Seat Parts: Cover clamps, brackets, seat posts, and structural connection pieces.
 
Aluminum, titanium, and stainless steel are common material choices, depending on weight, strength, finish, and application requirements.

Why Are Custom Bicycle Components Expensive?

Several factors can increase the cost of custom bicycle components:
 
  • Material Choice: Aluminum, titanium, and other performance metals require careful machining and handling.
  • Precision Machining: Tight tolerances and complex geometries demand more machine time and inspection. MachMaster supports tolerances up to ±0.01 mm.
  • Surface Finishing: Anodizing, sandblasting, polishing, and other finishes add extra processing steps.
  • Custom Engineering: Prototypes and specialized designs may require DFM review and additional setup before production.
  • Quality Control: Detailed inspection helps maintain consistent dimensions and reliable fit.
 
The higher price reflects the added precision, customization, finishing, and production control required for performance-focused bicycle parts.

Common Surface Finishes for Custom Bicycle Components

Custom bicycle componets often use surface treatments to improve appearance, durability, and corrosion resistance:
 
  • Anodizing: Strengthens the oxide layer on aluminum while adding wear resistance and color options.
  • Sandblasting: Produces a clean, matte texture and helps create a uniform surface.
  • Polishing: Smooths the metal for a brighter, more refined appearance.
  • Plating: Adds a protective metal layer to improve corrosion and wear resistance.
  • Powder Coating: Creates a tough, durable finish suitable for parts exposed to regular use.
 
MachMaster supports these finishing processes for custom metal components.

Key Features of Custom Bicycle Components

Custom bicycle components are designed around performance, fit, durability, and visual detail:
 
  • Precision Fit: CNC machining supports tight tolerances for accurate assembly and consistent performance.
  • Lightweight Design: Aluminum and titanium help reduce weight while maintaining useful strength.
  • Custom Geometry: Complex shapes, mounting points, and specialized dimensions can be produced for specific bike designs.
  • Durable Construction: Machined metal parts can withstand repeated riding loads and everyday wear.
  • Flexible Finishes: Anodizing, polishing, sandblasting, and coating provide both protection and visual customization.
  • Brand Customization: Logos, colors, and distinctive details can help create a recognizable product identity.

Popular Brands Specializing in Custom Bicycle Components

Several brands are well known for precision-made and customizable bicycle components:
 
  • Wolf Tooth Components: Produces machined chainrings, pedals, headsets, drivetrain parts, and accessories with a strong focus on in-house manufacturing.
  • Paul Component Engineering: Known for American-made aluminum brakes, levers, cranks, and other distinctive bicycle components.
  • White Industries: Specializes in precision hubs, cranks, bottom brackets, headsets, and other premium components.

Conclusion

Custom bicycle parts combine precision machining, tailored designs, and durable materials to improve fit and performance. CNC manufacturing also supports tight tolerances, complex geometries, and finishing options such as anodizing, polishing, and sandblasting.

Although custom parts often cost more than standard components, they offer greater flexibility and design control. For brands creating premium bicycle products, CNC machining provides a practical path from prototype to small-batch or larger-scale production.
