### **Product Introduction: Alloy A-286 / Incoloy A-286 Wire** **Precision-Drawn for High-Strength and High-Temperature Applications** **Incoloy A-286 Wire** is a premium iron-nickel-chromium superalloy wire, supplied in a form optimized for the manufacture of high-integrity components. Renowned for its ability to be precipitation-hardened to very high strength levels, A-286 wire retains excellent oxidation resistance and good fatigue properties at temperatures up to 1300°F (704°C). This combination makes it the foremost choice for critical applications where reliability under extreme stress and temperature is non-negotiable. Our A-286 wire is precision-drawn to exacting diameters and surface finishes, ensuring consistent performance and superior manufacturability for fasteners, springs, welding, and other demanding uses. --- #### **1. Chemical Composition (Weight %)** The composition is tightly controlled to ensure optimal response to heat treatment and consistent performance in the final product. | Element | Content (%) | | :--- | :--- | | **Iron (Fe)** | Balance | | **Nickel (Ni)** | 24.0 - 27.0 | | **Chromium (Cr)** | 13.5 - 16.0 | | **Molybdenum (Mo)** | 1.0 - 1.5 | | **Titanium (Ti)** | 1.9 - 2.35 | | **Manganese (Mn)** | 2.0 max | | **Silicon (Si)** | 1.0 max | | **Aluminum (Al)** | 0.35 max | | **Vanadium (V)** | 0.10 - 0.50 | | **Boron (B)** | 0.001 - 0.010 | | **Carbon (C)** | 0.08 max | | **Phosphorus (P)** | 0.025 max | | **Sulfur (S)** | 0.025 max | *Strengthening Mechanism:* The precise balance of **Titanium (Ti)** and **Aluminum (Al)** enables the formation of the gamma prime (γ') phase during age-hardening, which is the primary source of the alloy's exceptional strength. --- #### **2. Physical Properties** | Property | Value | | :--- | :--- | | **Density** | 0.290 lb/in³ (7.93 g/cm³) | | **Melting Range** | 2550 - 2600°F (1399 - 1427°C) | | **Specific Heat** | 0.11 Btu/lb-°F (460 J/kg-°K) | | **Thermal Conductivity** | 9.5 Btu-ft/hr-ft²-°F (at 212°F / 100°C) | | **Mean Coefficient of Thermal Expansion** | 9.2 x 10⁻⁶ per °F (16.6 x 10⁻⁶ per °K) from 70-1000°F | | **Modulus of Elasticity (Tension)** | 29.5 x 10⁶ psi (203 GPa) | --- #### **3. Mechanical Properties (Typical for Age-Hardened Condition)** A-286 wire is typically supplied in a solution-annealed condition for subsequent forming and is then age-hardened to achieve its peak strength. | Property | Solution Annealed (Typical) | Age-Hardened (Standard - per AMS 5732) | | :--- | :--- | :--- | | **Tensile Strength** | 95 - 110 ksi (655 - 760 MPa) | 150 ksi (1035 MPa) min | | **Yield Strength (0.2% Offset)** | 45 - 60 ksi (310 - 415 MPa) | 95 ksi (655 MPa) min | | **Elongation** | 35% min | 15% min | | **Hardness** | Rb 85 max | Rc 28 - 38 | *Note:* For specific applications like fasteners (AMS 5734), even higher strength levels are often specified and achieved. --- #### **4. Product Applications** Incoloy A-286 Wire is the base material for a wide range of critical, high-stress components. * **Aerospace & Jet Engines:** * **High-Strength Fasteners:** The primary application. Used for bolts, studs, screws, and nuts in jet engine casings, afterburners, and airframes where high shear and tensile strength are required at elevated temperatures. * **Springs:** Latching, retainer, and compression springs that must maintain load and resist relaxation under high thermal cycles. * **Turbine Blade Retainers** and **Lockwire**. * **Industrial Gas Turbines:** * Bolting and fastening for turbine casings and hot-section components. * Welding wire for repair and fabrication of A-286 components. * **Automotive & Motorsport:** * **Turbocharger Hardware:** Studs and nuts that secure turbocharger housings to high-temperature exhaust manifolds. * **High-Performance Engine Valves** and valve springs. * **General Engineering:** * **Welding Wire:** Used as a filler metal for joining A-286 components and for overlaying on other steels for corrosion and heat resistance. * **Screens** and **Mesh** for high-temperature filtering. --- #### **5. International Standards** Our Alloy A-286 Wire is manufactured to meet the most stringent international standards for quality and performance. **Primary Material Standards for Wire:** * **AMS:** **AMS 5732** (Wire, Age-Hardenable), **AMS 5734** (Wire, for High-Temperature Fasteners) * **ASTM:** Not as commonly wired-specific as AMS, but falls under the umbrella of ASTM A453 (Grade 660). * **UNS:** UNS S66286 * **EURONORM:** 1.4980 **Common Specifications:** * **Diameter Range:** Available from fine diameters (e.g., 0.5mm / 0.020") to larger coils for bar stock (e.g., 12mm / 0.5"). * **Condition:** Supplied in Solution Annealed, or Solution Annealed and Pickled condition, ready for cold forming and subsequent age-hardening. * **Finish:** A bright finish is standard, with other finishes available upon request. --- #### **Why Choose Our Alloy A-286 Wire?** * **Consistent Quality:** Our wire is produced with rigorous process controls to ensure uniform chemistry, grain structure, and mechanical properties from coil to coil. * **Superior Surface Finish:** Precision drawing minimizes surface defects, which is critical for preventing fatigue crack initiation in high-stress components like springs and fasteners. * **Optimized for Manufacturing:** Supplied in the ideal condition for cold heading, thread rolling, and spring coiling, resulting in excellent tool life and formability. * **Guaranteed Performance:** Every lot is supplied with a full Mill Test Certificate (MTC/CMTR) providing traceability and verification that the material meets specified standards like AMS 5732. * **Technical Expertise:** We provide support to help you select the right wire specification and heat treatment cycle for your specific application. **For detailed specifications on available diameters, packaging, and technical data sheets, please contact our sales team.
