• Material: In order to provide high-quality sandblasting nozzles, high broad nozzles are generally made of several different materials. We offer nozzles with an aluminium jacket as well as nozzles with a rubber jacket. The question here has to do with where the nozzle is used. The nozzle with an aluminium jacket is the tougher version. But the more impact-resistant nozzle, as in cases of frequent falls or bumping during construction, for example, is the nozzle with a rubber jacket.

  The determining factor in the selection of the right nozzle is certainly the choice of the right nozzle liner. At high broad, we essentially distinguish among three different liners:

• Tungsten carbide: This material is very tough and abrasion-resistant, and as such is the most resistant to impact. Therefore it is especially suitable for use on construction sites where the nozzle is also subject to frequent impacts, for example.
• Silicon carbide: Silicon carbide provides a good mixture of impact and abrasion resistance. This material is more abrasion-resistant than tungsten carbide, but on the other hand is more sensitive to impacts. Therefore, nozzles with silicon carbide liners are good all-round nozzles for everyday use in different places and with different blast media.
• Boron carbide: This material is extremely abrasion-resistant and thus is especially durable. Therefore it is particularly suitable for extremely sharp-edged and/or aggressive blast media like corundum and garnet, as well as for multiple-shift operations and daily use. But it is somewhat more sensitive to impacts and thus suitable for stationary applications.

• In general, however, these are just rough guidelines and every user must find the right liner for his work and the right price-performance ratio for himself. Apart from the structure of the nozzle, the handling of the nozzle also plays a determining role in the durability, and thus of the economic success of the blasting work.
