What aluminum alloys do you work with? |
| We specialize in heat-treatable aluminum alloys — primarily the 6xxx series (6061-T6, 6082-T6), 7xxx series (7075-T6), and 2xxx series (2014, 2024). These alloys are selected for their strength-to-weight ratio, machinability, and response to T6 heat treatment. We do not work with non-heat-treatable series such as 1xxx, 3xxx, or 5xxx. |
What is the difference between 6061-T6 and 7075-T6? |
| 6061-T6 offers a good balance of strength, corrosion resistance, and machinability (tensile strength ~310 MPa), making it suitable for general structural components, bicycle parts, and robotics. 7075-T6 is significantly stronger (tensile strength ~572 MPa) with a higher strength-to-weight ratio, ideal for high-load applications such as UAV frames and aerospace components — though at higher material cost and with less corrosion resistance. |
Can you verify the elemental composition of incoming raw materials? |
| Yes. We use a Bruker Q4 TASMAN Optical Emission Spectrometer (OES) to analyze the elemental composition of every incoming aluminum billet batch. Results are verified against ASTM specifications and are also used as input variables for phase transformation calculations to optimize heat treatment parameters. |
How do you determine optimal heat treatment parameters for each alloy? |
| We use thermodynamic phase transformation calculations based on the actual elemental composition measured by OES. For each batch, we generate a CCT (Continuous Cooling Transformation) diagram and liquid-solid transformation curve to determine the correct solution treatment temperature, quenching rate, and aging conditions. For AA6061, our validated parameters are: T4 at 530–550°C, quenching at 50°C/s, and T6 aging at 177°C. |
What alloy series do you recommend for UAV / drone structural parts? |
| We recommend 7075-T6 for high-stress UAV structural components such as arm connectors and motor mounts due to its superior tensile strength (~572 MPa) and fatigue resistance. For non-critical brackets or covers where weight reduction is prioritized over ultimate strength, 6061-T6 is a cost-effective alternative. |
Can you source raw material, or does the customer need to provide billets? |
| We handle raw material procurement as part of our standard service. We source aluminum billets from qualified suppliers and perform incoming inspection (OES elemental analysis) on every batch. Customers may also supply their own material if required — please discuss with us prior to order confirmation. |
What is your production workflow from raw material to finished part? |
| Our standard workflow:
Step 1
Incoming material OES inspection Step 2
Billet cutting & heating Step 3
Aluminum forging (die forging) Step 4
Edge trimming Step 5
Solution treatment (T4) Step 6
CNC machining Step 7
Aging treatment (T6) Step 8
Surface treatment Step 9
Dimensional inspection (CMM) Step 10
Final visual inspection & packaging. Steps may vary depending on part requirements. |
Do you offer robotic forging? |
| Yes. We operate a robotic arm forging system integrated with our forging presses. Robotic forging improves process consistency, reduces operator variability, and enables precise control of billet placement and forging sequence — resulting in more uniform grain flow and tighter dimensional tolerances. |
Can you handle forging and CNC machining under one roof? |
| Yes. Forging, heat treatment, and CNC machining are all performed in-house. This eliminates inter-factory logistics, reduces lead time, and allows our engineering team to coordinate process parameters across the full production flow — which is critical for achieving consistent mechanical properties. |
Do you provide heat treatment in-house? |
| Yes. We have in-house heat treatment furnaces for both solution treatment (T4) and aging (T6). In-house control means we can fine-tune quenching rates and aging temperature/time for each alloy batch based on our OES analysis and phase transformation modeling, rather than applying generic parameters. |
