The high and low temperature tensile testing machine has become a material testing instrument for multiple cutting-edge and basic industries
Date: 2025-12-23Read: 0
The high and low temperature tensile testing machine is a material testing equipment that integrates mechanical loading and environmental simulation. It can test the mechanical properties of metals, polymers, composite materials, etc. in tension, compression, bending, etc. at temperatures ranging from -70 ℃ to+350 ℃. Its core value lies in revealing the strength, ductility, elastic modulus, and fracture behavior of materials under thermal mechanical coupling conditions, providing key data for product safety design and life prediction. With this capability, high and low temperature tensile testing machines have become material testing instruments in multiple cutting-edge and fundamental industries.
1、 Aerospace
In the certification of aircraft engine blades, fuselage aluminum alloy, and carbon fiber composite materials, it is necessary to simulate high-altitude low temperature (-55 ℃) and high temperature near the engine (>200 ℃) working conditions. The high and low temperature tensile testing machine verifies the tensile strength and fatigue performance of materials under temperature changes, ensuring that the aircraft structure remains reliable under the dual challenges of "cold brittleness" and "hot softening".
2、 New energy vehicles
The diaphragm, electrode material, and aluminum/magnesium alloy body parts of the power battery need to maintain mechanical stability between -40 ℃ (extremely cold in winter) and 80 ℃ (fast charging and heating). This device is used to test the puncture strength of membranes, adhesive shear force, and high-temperature creep performance of lightweight components, supporting the improvement of electric vehicle safety and endurance.
3、 Electronic appliances
Mobile phone flexible screens, chip packaging adhesives, and solder joint materials undergo thermal cycling during repeated power on and off cycles. By conducting high and low temperature tensile tests to match the thermal expansion coefficient and interface bonding strength, it can prevent cracking, delamination, or functional failure caused by thermal stress and improve the durability of electronic products.
4、 Rail Transit
Stainless steel, rubber sealing strips, and damping materials used in high-speed rail bodies need to maintain toughness and sealing performance at temperatures ranging from -40 ° C (severe cold in the north) to 70 ° C (summer exposure). The testing machine simulates the real service environment to ensure that the train does not break brittle in extreme cold and does not deform in high temperature.
5、 Biomedical
Medical titanium alloys and biodegradable polymers (such as PLA) are subjected to long-term stress at 37 ℃ in the human body, and the mechanical attenuation during their degradation process needs to be accurately monitored. Some studies simulate local warming of inflammation (40-42 ℃) to evaluate the stability of materials under pathological conditions.
