What is an aluminum foil tensile testing machine?
The aluminum foil tensile testing machine is a device specially used to test the mechanical properties of aluminum foil materials. It is widely used in packaging, electronics, aerospace and other industries. It can accurately measure key parameters such as tensile strength, elongation at break, and elastic modulus of aluminum foil, providing scientific basis for product quality control and production process optimization. The following is a detailed introduction to the aluminum foil tensile testing machine.
1. Working principle of aluminum foil tensile testing machine
The aluminum foil tensile testing machine fixes the aluminum foil sample through a clamp and applies axial tension until the sample breaks. During this process, the sensor records tension and displacement data in real time, and generates a stress-strain curve through software analysis to calculate various mechanical indicators.
| test items | Test standards | Typical value range |
|---|---|---|
| tensile strength | GB/T 228.1-2021 | 80-200MPa |
| Elongation at break | ISO 6892-1 | 1%-10% |
| elastic modulus | ASTM E111 | 60-80 GPa |
2. Core components of aluminum foil tensile testing machine
1.Load system: The servo motor drives the ball screw to achieve high-precision force loading.
2.sensor: Using high-precision strain gauge sensors, the measurement range is usually 0.5N-50kN.
3.Fixture system: Standard pneumatic push clamp, optional high temperature clamp or special environment clamp.
4.control system: Full digital closed-loop control based on DSP, with sampling frequency up to 1000Hz.
5.software system: Supports automatic calculation, data export and report generation functions.
3. Technical parameters of aluminum foil tensile testing machine
| Parameter type | Technical indicators |

| Accuracy level | Level 0.5 (better than the requirements of GB/T 16825.1) |
| speed range | 0.001-1000mm/min |
| Valid itinerary | 800-1000mm |
| test space | 600mm (width) × 600mm (height) |
4. Application fields of aluminum foil tensile testing machine
1.Packaging industry: Test the mechanical properties of food packaging aluminum foil to ensure packaging integrity.
2.Electronics industry: Evaluate the mechanical properties of capacitor aluminum foil and optimize the production process.
3.Aerospace: Testing the interface bonding strength of aluminum foil composite materials for aviation.
4.Scientific research institutions: Carry out basic performance testing for new material research and development.
5. Key points for selecting aluminum foil tensile testing machine
1. Select the appropriate measuring range according to the thickness of the aluminum foil (it is recommended to use the 5kN model for conventional 0.006-0.2mm aluminum foil)
2. Consider whether an environmental chamber is needed (temperature range -70℃~350℃)
3. Pay attention to the type of clamp (pneumatic clamps can effectively prevent the specimen from slipping)
4. Confirm software functions (whether it supports multiple languages, customized reports, etc.)
6. Mainstream brands of aluminum foil tensile testing machines in the market
