Welcome to Hemaokang Steel (Shandong) Co., Ltd., a professional manufacturer dedicated to delivering high-performance metal materials for demanding industrial applications. Our 7075 Aluminum Rod 20mm Solid Round Bar 2m Cut-to-Size Surface Anodized for Aerospace Gears is engineered to offer high strength, corrosion resistance, and dimensional accuracy. This product is a suitable choice for gear shafts, precision machined parts, and aerospace components where reliability is non-negotiable.
The 7075 alloy is recognized as one of the strongest aluminum alloys available. When combined with a precise 20mm diameter, a practical 2-meter length, and a protective anodized surface, this bar becomes a versatile raw material for manufacturers who demand consistency and performance. Below we break down the key attributes that make this product stand out for aerospace and mechanical engineering use.
- High Strength: 7075 aluminum offers high tensile strength, making it suitable for structural and load-bearing applications.
- Solid Round Shape: The solid round bar profile provides uniform stock for machining gears, bushings, and other cylindrical parts.
- Precision Diameter: A 20mm diameter with consistent tolerances reduces material waste and machining time.
- Cut-to-Size Service: We supply the bar in standard 2m lengths and can cut it to your requested dimensions, minimizing handling and scrap.
- Anodized Surface: The anodized finish significantly improves wear resistance, corrosion resistance, and surface hardness.
- Aerospace Grade: Formulated and processed to meet the typical requirements of aerospace gears and structural components.
The following table outlines the standard specifications for this aluminum rod. Customized dimensions and processing options are available upon request.
| Specification | Detail |

| Material | 7075 Aluminum Alloy |
| Shape | Solid Round Bar |
| Diameter | 20mm |
| Length | 2m (custom cut lengths available) |
| Surface Treatment | Anodized |
| Temper | T6 / T651 (optional) |
| Application | Aerospace gears, machine parts, structural components |
| Quality System | ISO9001 certified plant |
In aerospace operations, gear materials must withstand high cyclic loads, friction, and environmental stress. The 7075 aluminum rod provides a favorable strength-to-weight ratio compared to steel, allowing for lighter assemblies without sacrificing mechanical integrity. The anodized outer layer forms a hard, inert film that protects the bar from oxidation and abrasive wear, which is critical for gear teeth and bearing surfaces.
Our manufacturing process includes careful cutting to maintain square and burr-free ends. This means you can immediately load the rod into CNC lathes or milling machines. Cut-to-size availability helps reduce inventory and logistics costs, as you order only the lengths you need. Whether your workshop needs a single 20mm bar or multiple production batches, we accommodate both.
The 20mm diameter is a popular size for gear shafts and bushing blanks, offering enough cross-section to handle moderate torque while still allowing efficient machining. The 2 meter length provides flexibility for multiple parts from a single bar. Our cutting service can divide the rod into exact lengths such as 100mm, 250mm, or 500mm, reducing secondary operations and scrap. For even greater convenience, we can bevel edges slightly to prevent damage during transport.
Every rod undergoes a series of checks including diameter measurement, visual surface inspection, and length verification. Samples are retained for internal testing. The anodized layer is applied in controlled baths to achieve a uniform finish, and the thickness can be adjusted to suit light or heavy service. If your company has specific requirements, our team can work with your drawings or specifications to ensure full compliance.
Key Benefits for Customers:
- Cost Efficiency: Less raw material waste and reduced machining steps.
- Time Saving: Ready-to-machine rod with consistent dimensions and surface finish.
- Reliability: Traceable quality under an ISO9001 quality management system.
- Flexibility: Optional cutting lengths, varied temper, and packaging options.
This bar is particularly suited for:
- Aerospace gear manufacturing and transmission components
- High-strength fasteners and fittings
- Precision shafts, spindles, and bushings
- General structural parts requiring corrosion resistance
- Prototyping and replacement parts for aviation systems
We understand that every project has unique requirements. Therefore, our cut-to-size service lets you specify lengths from 100mm up to 2m or longer, depending on logistics. We also offer different anodizing levels, such as standard or hard anodizing, to match your application. All rods are inspected during production to ensure diameter, straightness, and surface quality. If you need a material certificate or test report, our team can provide documentation in accordance with our ISO9001-controlled processes.
Hemaokang Steel (Shandong) Co., Ltd. was established in 2025, and despite being a rising producer, our export volume has already reached US$50 million to US$100 million annually. We operate with a dedicated team of 51–100 employees and ship primarily from Qingdao Port, ensuring efficient logistics to North America, Europe, Southeast Asia, Africa, the Middle East, and many other regions. Our facility operates under an ISO9001 certified quality management system, which reflects our commitment to consistent quality and management excellence. We invite you to contact us for detailed specifications, quotes, or custom requests. Let our 7075 aluminum rod become the dependable foundation for your next precision component.
Frequently Asked Questions
1. Can you cut the 7075 aluminum rod to custom lengths?
Yes, we offer cut-to-size services. You can specify exact lengths within practical limits, and we will supply the rod cut to your requirements. Contact us with your dimensions for an accurate quote.
2. What benefits does anodizing provide for this aluminum rod?
Anodizing creates a protective oxide layer on the surface. It improves corrosion resistance, increases surface hardness, and provides a more durable finish that resists scratches and wear. This is advantageous for moving parts like gears where surface friction matters.
3. Is the 20mm diameter maintained accurately?
Yes, the rod is manufactured to standard tolerances for round bar. We perform dimensional inspections to ensure the diameter meets spec, but exact tolerance values can be provided on request.
4. Is 7075 aluminum suitable for aerospace gears?
7075 aluminum is commonly used in aerospace applications due to its high strength and good fatigue resistance. However, the final suitability depends on the gear design, loading conditions, and applicable standards. Our engineers can help you assess the material for your specific use case.
5. What is the minimum order quantity?
We accept small trial orders as well as large volume orders. The minimum order quantity can be discussed based on your requirement and the cutting length. Please reach out to us for detailed terms.
6. Do you provide material certificates or test reports?
Yes, we can provide material certificates and test reports as part of our quality assurance. These documents are issued under the ISO9001 quality system, and we can include them with your shipment.
7. Which port do you ship from?
Our main port of shipment is Qingdao Port in China, which offers convenient access to international shipping routes. We handle exports to many countries across the globe.
8. Can I request a different temper or surface treatment?
Certainly. We can supply 7075 rod in T6 or T651 temper, and anodizing can be customized. Please specify your preferred options when placing an order, and our team will confirm availability.
