Wear Protection & Semi-Finished Products
Carbide solutions for extreme loads
Boehlerit offers a wide range of carbide semi-finished products for wear protection, including fine to ultra-fine grain grades with optimal cobalt content. They are characterized by high dimensional accuracy, low tolerances, and reliable performance values, making them ideal for demanding applications with heavy loads.
Electric mobility
Boehlerit is behind it!
Increasingly sophisticated vehicle concepts in electric mobility require ever more complex but at the same time more flexible tooling solutions from component manufacturers. The Austrian carbide and tool manufacturer Boehlerit is addressing precisely this point and offers a comprehensive range of tool and grade solutions for the production of a wide variety of components.
Precision tool manufacturing
Semi-finished products and blanks for precision tool manufacturers
Manufacturers of precision tools for wood, plastics or metal machining place very exacting demands in terms of metallurgical features and machinability. Two essential criteria are minimum dimensions and dimensional accuracy of semi-finished products and blanks. Boehlerit develops hard materials that meet the highest demands of our customers in machining and application and make economic processing possible. In many cases, cost-efficient production is only possible with perfect blanks. This is why cooperation with Boehlerit starts as early as in the project stage.

Forming industry
Carbide for every application
The selection of the carbide grade is especially important for this production sector, because worn or premature failure in tooling results in production stops which are costly. The choice out of more than 40 grades – from submicron grain carbides with 3 % cobalt to the course grained 26 % cobalt grade – enables Boehlerit to find the ideal solution for customers´ applications.
Wood processing
Boehlerit is part of the world wide Leitz Group of companies and has developed its own grade banding which are ideally suited to the wood working industry
The majority of grades found within this sector are made up of fine, submicron and ultrafine grain carbides with between 2 – 6 % cobalt. Special value is placed on the even grain distribution, where the benefits of fine grain material come in to being. Boehlerit fine grain carbides distinguish themselves through a high degree of cutting edge stability combined with good quality transverse rupture strength and reduced wear tendencies. The application of carbide tools is the requirement of cost effective and rationalized production. Boehlerit has the ability and the know how to support tool making companies with applications solutions. This applies to both wood and laminated materials. Boehlerit welcomes the closest inspection within the saw teeth sector, spiral carbide blades finished and semi-finished products for all aspects
of the industry.
Construction industry
Boehlerit engineers individual and customized roof tile tools
Boehlerit has been designing and manufacturing tungsten carbide tooling for the “Roof Tile“ and “Clay Industry“ for over thirty years and is recognised for being one of the pioneers within this complex technology. When compared to steel, our tungsten carbide tooling achieves between a twenty to thirty fold increase in tool life. To achieve product optimization, every Boehlerit roof tile tool is designed specially for the individual customers´ needs and operational conditions. We select the optimum carbide grade for each tool from our own production of seventy different types.
Specific industries
Carbide as construction material
Recent years have seen a marked increase in the use of carbides as construction components. The demand for a material that offers the highest possible level of reliability in highly diverse conditions comes from a wide range of industries, such as the chemical industry, plastics manufacturing, the food industry, oil and gas production, beam technology, the recycling industry and also the health and hygiene sector. One of the most sought-after characteristics of carbide is that it offers an outstanding level of safety and reliability, unrivalled by any other known material. Reliability is related to uncontrolled wear – and wear resistance is the most important characteristic of carbide. Where materials are also exposed to impact stress, high loads and/or pressure, high temperatures and/or corrosion, carbide is often the last one standing when it comes to dealing with all these factors.
The use of carbide makes sense in the following scenarios:
High quantity
High demands in terms of quality consistency of the manufactured products
Cost-effective production
As a rule, these factors apply to high-volume production scenarios, where resistance to abrasive and surface-damaging stress is key and materials have to withstand a high level of mechanical stress. Tools can be made from solid carbide or a compound of carbide and steel. The steel/carbide compound can be created by soldering, gluing or mechanical means of fastening. Experience has shown that the best construction solutions usually result from a close cooperation between applications engineers and carbide manufacturing engineers. It is highly advantageous to set up these contacts at an early stage of a given project, when it is still possible to adjust construction in such a way that it fully leverages the benefits of carbide.
Carbide raw material
In this manufacturing process the carbide granulate is densified cold isostactically under high pressure, achieving a very even density distribution in the blank
The blanks are then dewaxed and presintered at temperatures of between 700°C – 800°C in order to achieve the strength condition needed for the final processing. The presintered blocks are processed largely on CNC machines using diamond or PCD cutting tools and given the form demanded by the customer. The typical mechanical characteristics of this material unfold during the sintering process. This develops under strict control
in a gaseous atmosphere and temperatures of around 1350°C – 1500 °C and 100 bar pressure in the sinter-HIP ovens. Submicron grades and grains with a cobalt content of under 15 % benefit from considerable increases in transverse rupture strength.
