Description
2017A T4 Free Cutting Precision Tolerance Round Aluminum Bar Rod For CNC Automatic Lathe High Speed Machining Components
Product Overview

2017A T4 free cutting round aluminum bar is specifically formulated for high-speed CNC automatic lathe machining operations. With its copper-rich alloy composition and optimized grain structure, 2017A delivers superior chip breaking characteristics, reduced tool wear, and excellent surface finish quality—making it the go-to material for mass production precision components.

Key Features
  • Exceptional Machinability: Free-cutting grade aluminum with excellent chip formation and breakage for automatic lathes
  • High Production Efficiency: Enables faster cutting speeds and feed rates compared to standard 6061 aluminum
  • Precision Tolerance: Supplied in h8/h9 tolerance grades for consistent dimensional accuracy
  • Reduced Tool Wear: Optimized alloy composition minimizes cutting tool consumption
  • Excellent Surface Finish: Achieves superior surface quality directly from machining

Why 2017A for Automatic Lathes?

Unlike general-purpose 6061 which can produce long, stringy chips that tangle around tooling, 2017A T4 generates short, manageable chips ideal for automatic lathe operations. This results in faster cycle times, reduced downtime, and higher throughput in high-volume production environments.

Frequently Asked Questions
Q: What makes 2017A a free-cutting alloy?

A: Its copper and lead content promotes short chip formation and reduces cutting forces during machining.

Q: Is 2017A suitable for high-speed CNC lathes?

A: Yes, 2017A T4 is specifically designed for high-speed automatic lathe and CNC turning operations.

Q: What tolerance grade is available?

A: We supply 2017A bars in h8 and h9 precision tolerance grades.

Q: Can 2017A be anodized?

A: Anodizing is possible but the appearance may differ from 6000 series alloys due to its copper content.
