2 Tridelta s holdin manets take the strain of everyday work in numerous different branches of industry. Safe, reliable, and free from wear and tear, they are used for tasks as diverse as mountin, clampin and fixin, transport and measurin. Today, many firms successfully employ Tridelta holdin manets to undertake a wide rane of machine enineerin tasks. The quality of these manets is solidly based on some forty years of production experience at Thyssen-Manet. Today, Tridelta carries on the proven tradition of manufacturin hihperformance holdin manets. Such manets are chiefly used in machinin tasks, to orientate ferro-manetic work pieces to the desired position so they can be easily and safely measured-up and worked on, accident-free and without recourse to complicated mechanical means. 0 7 % St Mn Cr Automatic steels 0 Mn Cr W Permeability µ Fe GG I GG II Tridelta holdin manets make the difference when rationalisation production or seekin new, simpler manufacturin processes. % > 12 Surface rade ISO 1302 Construction of rod and flat rips These manet systems are so desined and constructed as to provide attractive at one surface only. Manetic does not emanate from any other part of the system. This desin makes it possible to delimit the manetic field such that it does not pass throuh the whole work piece or the mechanical elements surroundin it (except Secolit rips). 2

3 The s iven in subsequent tables are minimum values at room temperature and are measured by vertically separatin rips, attached with full surface contact, from soft iron or low-carbon steel work pieces of the requisite thickness. If the pole surface is dirty, or the work piece surface uneven, air aps appear, reatly reducin the attractive. Pole surfaces should be reularly inspected and cleaned whenever necessary. The holdin manets described here do not ae, retainin their attractive for an unlimited period of time. Only excessively hih workin temperatures or the proximity of powerful external manetic fields reduce their manetic potency (except Secolit rips). % Air ap mm Air ap Work piece Rod rip 6 Various materials influence attractive by chanin permeability. Increased impurities and alloy components tend to decrease permeability and subsequently attractive. Increased depth of surface rouhness of a work piece leads to reduced holdin capacity due to a dramatic reduction of attractive. In the same fashion, increasin the air-ap between the manet and the work piece, or insertin nonmanetic conductin material, reduces attractive. If you have any concerns about the possibly damain effects of lonterm temperature, fluctuatin temperature or chemical challene on manet performance, please do not hesitate to contact us.

4 Flat rips from Oxit Oxit flat rips are made from the ceramic permanent manet material, Oxit 300. A mild steel pot provides the required manetic shieldin. The small thickness of the flat rip has numerous constructional advantaes, and the material used makes these manets particularly economical. Oxit flat rips can withstand extended use at temperatures up to a maximum of 0 C without causin any structural chanes in the manetic material. However, heatin to this temperature can lead to a 30-0 % reduction in attractive, but this is reversible and there is no permanent loss of manetic.

5 Rod and flat rips in Secolit Secolit is an alloy of cobalt with various rare earth elements (e.. samarium). Compared to the other alloys, it enerates three to five times more attractive for the same size: or, of course, the same with reduced size. Secolit rod and flat rips can withstand extended use at temperatures up to a maximum of 0 C without causin any structural chanes in the manetic material. Heatin to this temperature can result in a 1 - % loss in attractive. However, this is reversible and the manets suffer no permanent loss of attractive. Methods of fixin: Pressin Gluin Screwin in place Under no circumstances should Secolit rod rips be pressed directly into iron as this short-circuits the manetism, dramatically reducin adhesive power. The clearances between the between the manet and its iron casin shown in the table must be maintained. The adhesive surface of manet types to and to can shaped as desired usin the appropriate rindin tool. Secolit flat rips are manetically shielded by a soft iron casin. The small thickness of the flat rip offers many advantaes. Their use is described in the instructions for mountin on pae x A Secolit rips are particularly suitable for use in the secondary zone of spot-weldin machines; demanetisation does not occur.

6 Rod rips from Oerstit Oerstit rod rips are constructed from a AliCo permanent manet material, Oerstit 00. Mild steel casin and interstitial sheath of non-manetisable material provide the necessary shieldin. Oerstit rod rips can withstand extended use at temperatures up to a maximum of 0 C without causin any structural chanes in the manetic material. Heatin to this temperature can result in a 30 0% loss in attractive. However, this is reversible and the manets suffer no permanent loss of attractive.
