**Product Introduction: Alloy 801 / Incoloy 801 Foil & Shim, UNS N08801** **Overview** Alloy 801 (Incoloy 801) foil and shim represent the thin-gauge forms of this titanium-stabilized nickel-iron-chromium alloy, engineered for specialized applications requiring precision thickness and exceptional high-temperature performance. Available in thicknesses typically ranging from 0.001" to 0.020" (0.025mm to 0.5mm), these ultra-thin materials maintain the alloy's characteristic oxidation resistance and strength while offering flexibility and precise dimensional control. The foil is supplied in rolled coils for continuous processing, while shim stock is provided as flat sheets for precision spacing and sealing applications. **Key Characteristics** * **Ultra-Thin Cross-Section**: Precision-rolled to tight thickness tolerances * **Superior Surface Finish**: Typically supplied with descaled, pickled, or bright finished surfaces * **Excellent Formability**: Can be stamped, blanked, and formed into complex shapes * **High-Temperature Integrity**: Maintains oxidation resistance up to 1100°C (2012°F) * **Consistent Mechanical Properties**: Uniform characteristics across entire length and width * **Good Weldability**: Suitable for resistance and laser welding processes **Chemical Composition (Weight %)** | Element | Content (%) | |---------|-------------| | Nickel (Ni) | 30.0 - 34.0 | | Chromium (Cr) | 19.0 - 22.0 | | Iron (Fe) | Balance | | Carbon (C) | 0.05 - 0.10 | | Titanium (Ti) | 0.15 - 0.60 | | Aluminum (Al) | ≤ 0.30 | | Manganese (Mn) | ≤ 1.50 | | Silicon (Si) | ≤ 1.00 | | Copper (Cu) | ≤ 0.75 | | Sulfur (S) | ≤ 0.015 | **Physical Properties** | Property | Value | |----------|-------| | Density | 7.95 g/cm³ (0.287 lb/in³) | | Melting Range | 1350-1400°C (2460-2550°F) | | Specific Heat (20°C) | 450 J/kg·K | | Thermal Conductivity (20°C) | 11.9 W/m·K | | Mean Coefficient of Thermal Expansion (20-1000°C) | 14.7 × 10⁻⁶/°C | | Electrical Resistivity | 1.00 μΩ·m | **Mechanical Properties (Typical for Annealed Condition)** | Property | Foil (0.001-0.010") | Shim (0.010-0.020") | |----------|---------------------|---------------------| | Tensile Strength | 520-690 MPa (75-100 ksi) | 550-720 MPa (80-105 ksi) | | Yield Strength (0.2% Offset) | 205-345 MPa (30-50 ksi) | 240-380 MPa (35-55 ksi) | | Elongation | 25-35% | 30-40% | | Hardness (Rockwell B) | 75-85 HRB | 78-88 HRB | **Product Applications** * **Thermal Management**: Thin heat shields, thermal barriers, and radiation baffles in high-temperature furnaces * **Precision Sealing**: High-temperature gaskets and custom-shaped seals for flanges and furnace doors * **Electrical Components**: Resistance heating element backing strips and electrical insulation spacers * **Aerospace**: Thin thermal protection systems, engine compartment shields, and instrumentation mounts * **Industrial Furnaces**: Interlayer insulation, winding strips, and protective wrapping for thermocouples * **Semiconductor Processing**: Boat components, wafer carriers, and diffusion furnace parts * **Custom Fabrication**: Stamped RFI/EMI gaskets, specialized washers, and precision shimming applications **International Standards & Specifications** * **ASTM Standards**: - ASTM B409: Standard Specification for Nickel-Iron-Chromium Alloy Plate, Sheet, and Strip (Foil and shim typically fall under the strip category with thickness < 0.187"/4.75mm) * **Aerospace Materials Specification**: - AMS 5512: Sheet, Strip, and Plate; Corrosion and Heat-Resistant (Covers foil and shim thickness ranges) * **Dimensional Standards**: - Thickness tolerance per ASTM A480 for stainless steel (commonly referenced) - Custom thickness tolerances available down to ±0.0001" for critical applications * **International Designations**: - UNS N08801 - Werkstoff Nr. 1.4875 - AFNOR NC 21 Fe D * **Quality Standards**: - Mill Certification to EN 10204 3.1/3.2 - Dimensional certification per customer specifications **Note**: Foil is generally defined as material under 0.006" (0.15mm) thickness, while shim stock typically ranges from 0.006" to 0.020" (0.15mm to 0.5mm). Both are supplied in various tempers (annealed, quarter-hard, half-hard) to suit specific application requirements. **Disclaimer**: The information provided is for reference purposes.
