Lever-Loaded Creep Testing Machine

The Lever-Loaded Creep Testing Machine is a classic creep testing system that applies a constant load through a lever-and-dead-weight mechanism. It is designed for long-duration mechanical testing of high-temperature alloys, titanium alloys, ferrous metals, and non-ferrous metals. The system can perform creep, stress-rupture, and crack growth/propagation tests, making it suitable for materials research, aerospace, energy, automotive, and other industries where long-term material behavior needs to be evaluated.

The mechanical loading principle provides a stable constant force for extended tests, while the modular fixture design allows the machine to be configured for different specimens, temperatures, and testing standards.

Application

The machine is suitable for:

(1) High-Temperature Alloy Testing：Evaluating the long-term deformation and rupture behavior of high-temperature alloys under sustained loading.

(2) Titanium Alloy Testing：Studying creep and stress-rupture properties of titanium alloys used in demanding service environments.

(3) Ferrous and Non-Ferrous Metals：Testing the long-term mechanical behavior of steel, aluminum alloys, copper alloys, and other metallic materials.

(4) Aerospace Materials：Evaluating materials intended for engines, structural components, and other applications exposed to sustained loads and elevated temperatures.

(5) Energy Industry：Supporting material evaluation for power-generation and other long-term high-temperature applications.

(6) Automotive Materials：Assessing the long-term mechanical stability of metallic materials and components.

(7) Materials Research and Quality Control：Providing long-duration test data for material development, production verification, and quality assessment.
