Hammer PM Sintered Parts

Product Introduction

Carbide strips have various grades according to their different properties and uses. The most commonly used customized cemented carbide breakers are YG series cemented carbide strips, such as YG8 tungsten steel strips, YG3X cemented carbide strips, YG6X tungsten steel strips, and YL10.2 cemented carbide strips, There are also YT series carbide strips, such as YT5 carbide strips, YT14 cemented carbide strips. Carbide breaking hammer also has YD201 cemented carbide square bar, YW1 cemented carbide bar, YS2T cemented carbide square bar, and so on. The physical and mechanical properties of different grades of cemented carbide bars are not the same, so you should choose carefully according to the conditions of use, environment, purpose, and requirements when purchasing.

The performance of cemented carbide is affected by the composition and structure of the hard phase and binder phase. Generally speaking, when the hard phase content is high and the crystal grains are fine, the hardness of the alloy is high, the wear resistance is good, and the impact resistance is poor. When there is a lack of carbon in the cemented carbide hammer alloy, the η phase (decarburization phase) appears, and the performance of the alloy becomes brittle. The cutting performance of the alloy insert is better, and the composition and structure of the binder phase also have an important impact on the performance of the cemented carbide. In the production of cemented carbide, Co is a good bonding metal. Compared with Ni and Fe, Co has better wettability with the hard phase, and the performance of the bonded cemented carbide is usually higher than that of Ni and Fe. Due to Ni's low magnetic properties and good corrosion resistance, WC-Ni is superior to WC-Co alloy in performance as a non-magnetic alloy or corrosion-resistant alloy. Customized cemented carbide breaker to strengthen the bonding phase, improve the performance of cemented carbide, and research new bonding phases with different components and structures. W and C are used to alloy Co to form a cobalt alloy with eutectic composition. Its theoretical eutectic temperature is 1280°C and its melting point is low, which is conducive to the densification of the sintered billet at low temperature.

With the rapid expansion of China's auto industry, the demand for cutting tools for auto parts processing is increasing, and the demand for cemented carbide in China's steel, transportation, construction, and other fields is also growing. In the strategic picture of foreign cemented carbide multinational companies, the Chinese market has quietly changed from a supporting role to a leading role. The analysis pointed out that by the end of the "Twelfth Five-Year Plan", my country's cemented carbide output will reach 30,000 tons, sales revenue will reach 30 billion yuan, and the output of deep-processed products will account for more than 40% of the total cemented carbide. Compared with the "Eleventh Five-Year Plan", the export will be doubled and strive to exceed 1 billion US dollars. Cemented carbide hammer manufacturers will develop in the direction of deep processing and tool matching; in the direction of ultra-fine, ultra-coarse, and coating composite structures; in the direction of circular economy, energy saving, and environmental protection; in the direction of precision and miniaturization develop.

① Tungsten-cobalt cemented carbide The main components are tungsten carbide (WC) and binder cobalt (Co). The grade of cemented carbide breaking hammer is composed of "YG" (the initials of the Chinese pinyin of "hard, cobalt") and the percentage of the average cobalt content.

② Tungsten-titanium-cobalt cemented carbide The main components are tungsten carbide, titanium carbide (TiC), and cobalt. Its grade is composed of "YT" (the initials of the Chinese pinyin of "hard, titanium") and the average content of titanium carbide. Tungsten titanium tantalum tool

③ Tungsten, titanium, tantalum (niobium) hard alloys. The main components of foreign cemented carbide breakers are tungsten carbide, titanium carbide, tantalum carbide (or niobium carbide), and cobalt. This type of cemented carbide is also called general cemented carbide or universal cemented carbide. Its grade is composed of "YW" (the initials of the Chinese pinyin of "hard" and "wan") plus a sequence number, such as YW1.
