The tungsten carbide safety hammer head produced and designed by CTIA GROUP is mainly used in glass-breaking scenarios. It is suitable for transportation emergency equipment such as vehicle-mounted safety hammers, buses, and passenger ships, efficiently breaking tempered glass to assist in escape. It can also be used in industrial auxiliary scenarios, such as emergency breaking of construction and protective equipment glass, stone processing, and metal specimen testing. The characteristics of tungsten carbide safety hammer heads include high hardness, excellent wear resistance, strong impact resistance, and good chemical stability.
CTIA GROUP and its parent company, CHINATUNGSTEN ONLINE, have been dedicated to the tungsten-molybdenum products industry for nearly 30 years. They specialize in providing flexible, customized global services for tungsten-molybdenum products, designing, manufacturing, and precisely processing various standard specifications, grades, and dimensional precision according to customer requirements, suitable for a wide range of applications.

In terms of hardness, the hardness of tungsten carbide safety hammer heads ranges from HRA89 to 93, which is higher than that of high-speed steel, and can meet the impact-breaking requirements of brittle materials such as tempered glass. Under relatively high-temperature working conditions, the hardness of the hammer head remains stable and does not significantly soften due to temperature fluctuations, ensuring glass-breaking performance in different environments.
Regarding wear resistance, CTIA GROUP’s tungsten carbide safety hammer heads contains tungsten carbide with high hardness and a stable structure, effectively slowing down wear during impact operations. In other words, after long-term emergency use, the hammer head tip can maintain a good shape, resisting blunting and excessive wear, extending the service life and reducing replacement frequency.

In terms of impact toughness, the cobalt binder phase in tungsten carbide safety hammer heads provides a certain degree of flexibility, allowing the hammer head to withstand instantaneous impact loads and reducing the risk of cracking or chipping during impact. Common industry grades YG6, YG8, and YG10X have bending strengths ranging from 2,400 to 2,800 N/mm2, enabling them to endure instantaneous forces during emergency glass-breaking while ensuring structural stability during use.
In terms of chemical stability, tungsten carbide safety hammer heads can resist corrosion from acidic and alkaline substances. They exhibit low oxidation at high temperatures and can maintain stable performance even in humid or mildly corrosive environments, without significant degradation in material properties due to environmental factors.
However, the performance of CTIA GROUP’s tungsten carbide safety hammer heads is not fixed and is influenced by material composition and production process parameters. “YG” is the designation for tungsten-cobalt tungsten carbide, and the following number represents the cobalt mass fraction. Differences in cobalt content affect the balance between hardness and toughness. For example, YG6 contains 6% cobalt, with relatively high hardness, suitable for compact, lightweight safety hammers, balancing weight and basic glass-breaking performance; YG8 contains 8% cobalt, offering a balance of hardness and toughness, suitable for most conventional emergency glass-breaking scenarios; YG10X contains 10% cobalt, providing superior toughness and excellent wear resistance, suitable for high-frequency, high-load usage scenarios.
