FEB 1952 51-4AA The Tewa.-Neustadt representatives complained that the wire from Hettstedt was sometimes of two different diameters since both warp and woof w_re were knotted together on the same spool. he $ettstedt men pointed out that this was unavoid.- able so long as each spool had to have a prescribed amount of wire (90 or 150 grams). Since only the loose end of a spool of wire is examined, the knotting together of wire of different ,diameters could occur without being noticed. It was therefore agreed upon at the meeting that, in the future, al-11 spools should be free from knots, even though some of the spools would thus be under the prescribed weight..

The main difficulty encountered at the beginning of the r i ckei 31i.rc screen One of the topics under disczu~sion at e. meeting, which rc-cportedly took place at Tewa-Neustadt at the under the chairmanship of Pryodko, was the quality of the nicke wire screen produced. Representatives o~' both the Walzwerk fuer Buntmetalle Hettstedt, producers of the nickel wise, and Tewa- Neustadt, producers of the wire screen, argued over thf causes for low quality screen. The latter ascribed flaws in the screen to flawfs in thi. wire, but the Hettstedt representatives succeeded in proving that the wire prc:,du(.-ed, there was of good quality and that poor quality screen was caused by inexpert handling of the wire during the weaving process. d,iw eter and determining the correct chemical composition for tJ~e b,3bt wire. CENTRAL INTELLIGENCE AGENCY SECRET/CONT_R0L - U. S. OFFICIALS O a` $ECURITY INFORMATION Program (presumably 1940) was the poor quality of the prt-lox?swri nic~krl wire which, it is believed, came from the Soviet Union. This wire cpntained too much sulphur. At. that time, the :Hettstedt plant did, or;.i_y the f3 rie ~Law: ng. Later, the plant started. doing its own pouring, rolling and pre-dr?nr.ng in order to produce wire of the desired quality. During this second phase of the program, the main difficulties consisted. of finding, by trial and error, the correct pouring, rolli rig and ar..neal n.g tempera- tures, determining the number of drawings needed. to produce wire oi cf rtain SECRET/C0NTRp1L - U,~ S. i 'FI:CIALS ONLY.

The wire is drawn from electrode nickel. which comes from Russi?a, but is believed to originate in the West. For a timer nickel of even poorer gual.-ity than, that usual..l.y received. arrived at the :flettstedt plant. This .ni.ck:el nay have been of Russian origin. 6. Until sometime in 1950, all raw nickel was poured into cylinders about 10 crm. in, diameter and. between 40 and 45 cm, in length. This was carried out by using the induction furnace in the laboratory of the Uettsted plant. 9 ti capacity of this furnace was one cylinder. Later, when production increasE?'l, ore of the furnaces in. the plant's foundry was used for the same purpose. Th i ;. furnace has a six:-cy~inder capacity. The weight of each cylinder has beer reported as 35 k$. Y Laboratory personnel are supposed. to be present when ric'kel is poured,, but when the pouring is done at the foundry, the work is often done by foundry personnel,. Nickel is rolled once a week., at which time three tons are rolled in from one and. one-half to two hours. Pre-c:-.awing ,also->e; about four hours. Fine drawing is carrifd. out in three consecutive eight-fhou- shifts with the aid of from twelve: to eighteeL fine-drawing machines. 7. The rolling mill has been a part of the plant since its foundation it 1911 and was constructed by the former Benrath machine factory which is now a part of Demag. The rolling equipment has deteriorated with age and from the lack of any important improvemr-nt. The four lathes used for turning the c,~u Lrtd9-rs (Rohlinge) are also very old and. often fail. These lathes have a ester height (Spitzenhoehe) of about 25 cm. The annealing furnaces iurchlaufgiu_hopfen), built by Siemens-Pl.ania according to specifications set by Hettstedt plant engineers, are electrically-operated and have an effecti-,rr, annealing Length for a two-meter section of wire. 8. Before the nickel, is poured into a cylinder, it is aralyzec, for cr+rhorr content. Should the carbon. content be excessive or insufficient., carbon is either removed by burning or added to the nickel. Test samples of the molten rickel are removed with a ladle shortly before pouring. These samples go to the l.aborat.ory, where they are examined spectrographically, and. by other unspecified mear:s, mainly for carbon, sulphur and lead content. Removal of excessive amounts of sulphur and . lead is done by passing hydrogen over the molten nickel at temperatures ranging. from 1.,000 to 1,0500 C. 9. The Hettstedt ,plant reportedly produces three tons of nickel wire Zen week,i.e. six working days of three shifts each. The plant sometimes operates on Sundays and holidays also. The plant also uses nickel as base material for an average of two to three tons per month of other nrodumota he ~.. i; inn wire. Some of these are, nickel wire for the radio industry, nickel ear ctrode>>, nickel tubing and bands, and nickel equipment for storage batteries. This type of production has sometimes been. as high as fix or eight tons in one month, because of increased. demands from radio and electrical equipment plants, such as AEG. 10. It was expected that the November 195:L output of nickel goods other than fine wire would reach between six and eight tons. Three tons of tubing and bands, as well as 600 to 800 kg. of nickel wi:.re, both part of the November 1951 output, were to go to AEA Berlin. As far as can be ascertained,, no part of the nickel products, other than fine wirer goes to the Russians, nor Ls it known whether or not the raw nickel used, for these other products has the same origin as the fine wire nickel. 11. Drawing dies are the most critical, i teas in fine nickel wire prod,t cti or . In order to reduce wear, the Hetts;ted.t plant is now using the. wEt-drawin.process in all stages of drawing, whereas this process was formerly used Only in the initial stages, until a certain, unspecified, caliber had been reached. In other production fields, the plant is, experiencing difficulty in procuz :rte; pure iron for the manufacture of, magnetic, equipment.
