Aluminum Material Options for Brake Arms

We offer multiple material grades to match your application’s performance needs, from daily street riding to extreme racing conditions.

💡 Fun Fact: 7075 aluminum has a tensile strength of up to 500MPa, almost as strong as some low-carbon steels, while still being 30% lighter! That’s why it’s the top choice for racing motorcycle parts.

Material Key Characteristics Typical Application
6061-T6 Aluminum Lightweight, excellent corrosion resistance, good formability, cost-effective Street motorcycles, daily riding, general aftermarket parts
7075 Aluminum Ultra-high strength, fatigue resistance, superior vibration damping Racing motorcycles, high-performance builds, off-road applications
Stainless Steel Inserts Wear resistance, prevents thread stripping, extends part lifespan Pivot connection points, high-wear areas of brake arms

CNC Machining Process

Our end-to-end process ensures every brake arm meets the strictest performance and precision standards, with full control over every step:

1

CAD/3D design verification & DFM review

2

Billet aluminum material preparation & inspection

3

3/5-axis CNC precision machining

4

Deburring & edge finishing

5

Surface treatment (anodizing/powder coating)

6

Dimensional inspection & functional testing

💡 Quick Tip: Our 5-axis machines complete all operations in one setup, eliminating re-fixturing errors and cutting lead time by 30% compared to traditional 3-axis machining!

Surface Finishing Options

We offer a range of surface treatments to enhance corrosion resistance, durability, and the look of your brake arms:

Type II Anodizing

Hard, corrosion-resistant finish available in multiple colors, perfect for most street and racing applications.

Type III Hard Anodizing

Ultra-hard wear-resistant finish, ideal for off-road and high-wear racing parts.

Powder Coating

Thick, durable finish with excellent UV resistance, great for custom color branding.

Laser Engraving

Custom logo or part number engraving, permanent and wear-resistant for your brand.

Dimensional Accuracy & Quality Control

For critical safety parts like brake arms, precision and consistency are non-negotiable. We run full inspection on every batch to ensure compliance:

Inspection Item Our Standard
General Tolerance ±0.01mm
Surface Roughness Ra 1.6
Hole Position Accuracy ±0.02mm
Thread Inspection GO/NO-GO Gauge
Material Certification Available upon request

We use CMM (Coordinate Measuring Machine) inspection for critical dimensions, plus batch fatigue durability testing to ensure every part meets safety standards.

OEM Motorcycle Brake Arm Project

US Aftermarket Brand Custom Order

Customer Requirement

Lightweight rear brake arm for Dyna model motorcycles, 7075 aluminum with black anodized finish, 3000 pcs monthly batch.

Core Challenge

The client had issues with deformation during anodizing with their previous supplier, plus inconsistent thread precision that caused assembly issues.

Our Solution

We optimized the fixture design for anodizing, added post-anodizing thread calibration, and built CNC compensation programming to counteract material distortion.

Final Result

  • Part weight reduced by 18% compared to the client’s old part
  • Batch rejection rate dropped to below 1.2%
  • 100% assembly fit rate, eliminating client’s rework cost

Applications

Our custom brake arms are built to serve a wide range of motorcycle aftermarket and OEM applications:

Application Description
Racing Motorcycles Lightweight high-strength performance upgrades for track racing
Custom Bikes Personalized aftermarket parts for custom chopper and bobber builds
Off-road Motorcycles Enhanced durability parts for dirt bikes and adventure motorcycles
Aftermarket Modification Brands OEM component manufacturing for motorcycle modification brands
Motorcycle OEMs Mass production of standard components for motorcycle manufacturers
