Black Anodized 5-Axis CNC Milling Aluminum Alloy U Shape Bracket Custom

Brief Introduction

This custom 5-axis CNC machined aluminum U bracket features black anodized surface finish. Made of high-grade aluminum alloy, it delivers high rigidity, corrosion resistance and precise dimensional tolerance. It is widely used for automation equipment, optical instruments and mechanical assembly. OEM & ODM custom machining service is available. Factory direct supply with stable quality.

Product Overview

This U-shaped mechanical bracket is manufactured by advanced 5-axis CNC milling. The complex U-type structure and multi-hole positioning features can be completed in one clamping process, ensuring high assembly accuracy and good consistency. The workpiece adopts black anodizing surface treatment, which greatly improves wear resistance and anti-corrosion performance, and also achieves a neat and uniform black appearance.

All finished parts go through strict dimensional inspection before shipment. We support custom manufacturing according to your CAD drawings or physical samples, both prototype and mass production orders are welcome.

FAQ

Q1: What material is this U bracket?

A: Standard material is 6061 aluminum alloy. We also support 6063 and 7075 aluminum alloy for custom orders.

• 6061: General purpose, balanced strength and machinability, most widely used.
• 6063: Great anodizing effect for nice surface appearance.
• 7075: High-strength aerospace aluminum for heavy-load working conditions.

Q2: Can you produce according to my 2D or 3D CAD drawings?

A: Yes. Please send us your files in STEP, IGES or PDF format. Our engineering team will evaluate your drawing and provide quotation. We also accept physical samples for reverse engineering.

Q3: What is black anodizing? Can I choose other surface treatments?

A: Black anodizing is an electrochemical process to form a protective oxide layer on aluminum surface, improving corrosion resistance and wear resistance. Other options include clear anodizing, sandblasting, brushing and polishing.

Q4: What is your MOQ? Can I order 1 piece for sample testing?

A: MOQ is 1 piece. We support prototype sample before mass production.

Q5: What is your production lead time?

A: Sample order: 3–7 working days. Mass production: 7–20 working days depending on order quantity.

Q6: How do you guarantee product quality?

A: We inspect dimensions with calipers, micrometers and CMM. Every part will be checked before packing. Inspection reports can be provided upon request.

Q7: What is T/T payment term?

A: T/T stands for Telegraphic Transfer, also known as wire transfer. It is the most common international payment method. For sample orders, we accept 100% T/T in advance. For bulk orders, common terms are 30% T/T deposit before production and 70% T/T balance before shipment.

Q8: Can you also make parts from stainless steel or alloy steel?

A: Sure. We manufacture custom turned and milled parts in aluminum, stainless steel, alloy steel, brass and engineering plastics.
