Precision CNC Machining for 15-5 PH Aerospace Parts
When sourcing 15-5 PH aerospace parts, engineering and procurement teams face a specific set of challenges: managing the tough machining characteristics of precipitation-hardening stainless steel while meeting strict geometric tolerances and rigorous documentation requirements.
At AXALLOY Precision, we specialize in machining complex, high-value components from difficult alloys. Operating from Shenzhen, we provide international aerospace OEMs, Tier 1, and Tier 2 suppliers with a controlled, predictable manufacturing route—from initial prototype development through low-volume and repeat production.
If you have a complete 2D drawing and 3D model ready, we are prepared to evaluate your design and provide a detailed quotation.

What You Get When Partnering with AXALLOY
We understand that for aerospace projects, lowest unit price cannot come at the expense of manufacturability, process control, or communication. Here is how our capabilities directly benefit your project:
1. Reliable Schedules to Keep Your Assembly on Track
We do not just promise "fast delivery." We understand that delayed components stall entire aerospace assemblies. Our standard lead time of 10–20 business days (and 5–10 days for prototypes) is achieved through efficient fixture planning, in-house tooling strategies for hard alloys, and multi-axis machining.
For your team, this means predictable delivery dates, allowing engineers to validate designs faster and procurement to manage supply chains without emergency expediting.
2. Reduced Setup Errors for Complex Geometries
Aerospace structural components, manifolds, and brackets often feature thin walls, deep pockets, and critical interfaces. We utilize 3-, 4-, and 5-axis CNC milling alongside 9-axis mill-turn centers.
By machining your 15-5 PH parts in fewer setups, we maintain stronger feature relationships, delivering positional tolerances down to 0.010 mm and concentricity down to 0.008 mm. You receive parts that fit perfectly into your higher-level assemblies on the first try.
3. Frictionless Quality Compliance
Your quality engineers require hard evidence, not just assurances. We support your compliance requirements by providing complete traceability and documentation packages alongside your physical parts.
From raw material verification to final dimensional inspection, we provide the exact records your quality team needs to approve the parts and maintain your aerospace certifications.

Our Approach to 15-5 PH Stainless Steel
15-5 PH (Precipitation Hardening) is highly valued in aerospace for its high strength, excellent transverse toughness, and corrosion resistance. However, it requires specific machining expertise to manage tool wear, heat generation, and material behavior during cutting.
Before we cut any chips, our engineering team reviews your drawings. We evaluate the material state, geometry, and tolerances to define the optimal machining process.
If we identify features that could cause warping or excessive tool deflection during the machining of your 15-5 PH aerospace parts, we provide actionable Design for Manufacturability (DFM) feedback. This proactive approach prevents wasted material, avoids schedule delays, and stabilizes the production process for repeat orders.
Proactive DFM feedback prevents wasted material, avoids schedule delays, and stabilizes production for repeat orders.
Inspection and Quality Documentation
Aerospace parts are only as good as the documentation that accompanies them. Our temperature-controlled inspection room is equipped with calibrated CMMs (Accuracy up to 1.8 + L/300 μm), optical measurement systems, and hardness testers to verify every critical feature.
