Bend Testing Machine for Metals
A guided bend testing machine that applies controlled bending force to metal bars or sheets to assess ductility and formability. It is used to evaluate the mechanical properties of metals, specifically their ability to withstand deformation without cracking, making it essential for quality control of rebar and tubes.
9024.10.00Brinell Hardness Testing Machine
A hydraulic or mechanical hardness tester that indents metal surfaces with a carbide ball under high load, measuring the diameter of the indentation to calculate the Brinell hardness number. It is specifically designed for testing the hardness of metals, a key mechanical property, and falls under the tariff item for metal testing machines.
9024.10.00Charpy Impact Testing Machine
A pendulum-based impact testing machine that strikes notched metal specimens to measure impact energy absorption, indicating the toughness and brittleness of metals. This apparatus is used to test the mechanical properties of metals, specifically their resistance to sudden forces, and is classified under the tariff item for metal testing machines.
9024.10.00Digital Fatigue Testing Machine
A servo-hydraulic system that cyclically loads metal samples to evaluate fatigue life under repeated stress, featuring digital controls and data logging. It is designed to test the strength and elasticity of metals over time, making it a machine for testing mechanical properties of metals under tariff item 9024.10.00.
9024.10.00Portable Metal Hardness Tester
A handheld rebound hammer device that measures metal hardness via impact velocity ratio, rebounding off the surface.
