Q1: What material options for this 5-axis milled structural bracket?

A1: 6061-T6 aluminum is the standard choice for general structural use. 7075 aluminum is available for higher strength requirements. Other metals can be quoted upon request.

Q2: Why choose 5-axis CNC machining for this hollow bracket?

A2: This part has complex angled cavities and contoured surfaces. 5-axis machining can finish multi-side features in one setup, avoiding re-clamping errors and guaranteeing tight geometric tolerances.

Q3: What surface treatments can be applied on aluminum brackets?

A3: We provide deburring, anodizing, hard anodizing, sandblasting, chemical conversion coating. Anodizing greatly improves corrosion resistance and surface hardness.

Q4: Can you produce samples before mass production?

A4: Yes. We accept prototype samples first. Our engineering team will do DFM review before manufacturing to optimize manufacturability.

Q5: How to get a quotation?

A5: Please send your 2D & 3D drawings, material spec, quantity and surface treatment requirements. We will evaluate and provide competitive quote quickly.
