ODM CNC Metal Machining Parts Stainless Steel Aluminum Alloy Cnc Mechanical

Product Specification

Premium Aviation Aluminum – Superior All-Round Performance

Made from high-strength 6061/7075 aluminum alloy bar stock, machined as a single piece through CNC turning and milling:

Lightweight & High Strength – Density far lower than steel, greatly reducing equipment weight while providing excellent tensile and bending strength. Suitable for automotive, precision instruments, and other applications with lightweight requirements.

Corrosion & Rust Resistant – Aluminum alloy naturally forms a passive protective layer. Anodizing and ceramic coating are available. Withstands salt spray, grease, moisture, acids, and alkalis in harsh industrial environments.

Good Thermal Conductivity – Suitable for hydraulic and pneumatic lines. Dissipates heat quickly, ensuring long-term stable operation of piping systems.

Precision CNC Machining – Accuracy & Sealing Performance Maximized

The entire process uses precision CNC turning to achieve a tight, seamless structure adapted for universal joint connections:

Precise Tolerances – Ball port diameter, stepped shaft, and positioning step dimensions are held to ±0.01mm. Hole walls are smooth and burr-free, providing excellent fit with matching ball studs and line seals – eliminating leakage.

One-Piece Formed Structure – The ball stud and connecting shaft are machined as a single integrated piece with no welds or joints. High fatigue resistance, resisting fracture or loosening under long-term high-frequency oscillation and vibration.

Two Configurations Available – One design accommodates an embedded seal, the other is a straight-through hole. Directly usable for universal articulated joints, oil line connectors, and linkage connectors – easy installation and flexible angle adjustment.

Multi-Scenario Versatility – Broad Industrial Adaptability

This fitting is highly versatile, covering core applications across multiple industries:

Automotive Industry – Brake line fittings for motorcycles/automobiles, hydraulic linkage rods, shock absorber universal connectors

Fluid Power Systems – Universal joints for hydraulic and pneumatic lines, quick-connect fittings for equipment oil circuits

Machinery & Equipment – Adjustment linkage rods for automation equipment, hinged fittings for instruments and meters, movable connection joints for tooling fixtures

Outdoor / Marine – Lightweight line fittings with seawater corrosion resistance for ships and construction machinery

Full Range of Surface Finishes – Strict Quality Control

Available Processes – Natural polished finish, hard anodizing, nano-ceramic coating. Ceramic coating significantly improves surface hardness, wear resistance, and scratch resistance, extending service life.

Full-Process Quality Control – Incoming material inspection → CNC machining → deburring → full dimensional inspection → surface finishing → final product inspection. Sealing performance, concentricity, and appearance are strictly controlled – no defects.

Environmentally Compliant – Material meets RoHS standards. Material certificates and test reports are available – suitable for export and high-end equipment projects.

Flexible Customization – Fast, Efficient Delivery

We offer one-stop custom services:

• Customization of port diameter, shaft diameter, length, angle, and straight/blind hole configuration based on drawings or samples.

• Alternative materials available: stainless steel and carbon steel for high-pressure, heavy-load conditions.

• Standard sizes in stock for immediate shipment. Non-standard custom parts: 3–7 days for samples; stable delivery for mass production orders.

• Small trial batches and large-volume production both supported – outstanding cost-effectiveness.
