Uoeganaes unveils powder process FERROUS powder producer Hoeganaes Corp (Cinnaminson, NJ, USA) has developed a new process that it says produces bonded, premix metal powders with significantly improved properties and at lower costs than comparable Distaloy-produced products. The process, Ancorloy engineered bonding technology (EBT), is already being used to produce two products - Ancorloy 2 and Ancorloy 4. These powders are equivalent, in composition, with Hoeganaes’ Distaloy AB and Distaloy AE, respectively. This is the first time that a bonded premix with Distaloy characteristics has been manufactured. “This new technology will provide our customers with meaningful advantages in improved product properties, lower costs, and availability,” says Dennis M. Jackson, VP, sales and marketing. Jackson says Ancorloy EBT is a derivative of ANCORBOND processing technology for producing bonded premix metal powders. “As a result of using this advanced processing method we are seeing improvements of
Ancorloy
between 10 to 15% in fatigue, tensile, and impact strength in the Ancorloy products compared with Distaloy products of equal composition,” he says. The ANCORBOND process produces binder-treated material. Hoeganaes says the process overcomes the problem of product segregation, improves product flow and die fill, and provides consistent sectional densities, weight distribution, and alloy homogeneity. The company says these advantages have helped fabricators to improve production rates and have virtually eliminated part-to-part variability during production. Hoeganaes has been importing Distaloy products from Sweden for its customers, but the new Ancorloy products will be manufactured at its Milton, PA, plant. “Obviously, producing these products domestically, rather than importing them from Europe, will result in lower costs. In addition, delivery schedules will be greatly improved,” Jackson emphasizes. Hoeganaes Corp; tel: +l609-829-2220; fax: +1-609786-2574.
TecSyn PMP continues market success Inc TECSYN PMP (Huntsville, AL, USA) has received a production tooling order representing annual sales of US$SOO 000 for cylinder liners produced with its patented cold isostatic compaction process. This latest order, from a major North American small engine manufacturer, follows similar agreements signed with the same customer in November and December 1998. In total, the three orders represent annual sales of $7.8 million. The company uses the CIPS technique (dry bag cold isostatic compaction technology) originally developed in Sweden by a subsidiary of 4 MPR April 1999
to find
Hoganas AB. The process produces aluminium cylinder liners that, compared with traditional steel sleeves, offer several advantages including lower fuel emissions, reduced wear and lower noise levels. They also confer a weight reduction. TecSyn PMP, a division of TecSyn International Inc, has begun commercial production of the cylinder liners using its existing infrastructure. With the new orders, the division is expected to reduce its operating losses in 1999 and be profitable in 2000. TecSyn; tel: +l-905-687. 8811; fax: +l-905-687-6917.
Strong sales in Europe see Hiigands sales up 4% in 1998 FERROUS powder producer Hogan& AB enjoyed a 4% increase in turnover in 1998, with sales reaching SEK2210 million (US$269 million). A weakening of the Swedish krona corresponded to 1% in additional turnover, while a one-off sale of factory equipment contributed SEK22 million. Sales volumes for the year rose 1% to 222 740 tonnes compared with the 1997 figure, thanks primarily to a 6% increase in Europe (119 640 tonnes). Shipments were down 6%) overall in Asia (88 440 tonnes), due to drops of 6% and 34% in Japan and South Korea respectively. For powder metallurgy (PM) applications, sales volumes increased 2% overall. The rise in Europe was 8% to 89 299 tonnes, despite a very weak market in Eastern Europe where sales fell by 40%. Japan was down by 8% (26 000 tonnes) and South Korea by almost 40%. Volumes expanded, however, in most other Asian markets with Taiwan,
India and China increasing 6,11 and 29% respectively for sales Hoganas’ welding electrodes were down 10% in volume terms to 24 200 tonnes, while shipments for chemical and metallurgical applications fell 1% to 34 800 tonnes. Shipments of thermal coating powders increased 10% to 1140 tonnes. Hogan&’ operating income for the year totalled SEK538 million, 7% up on the 1997 figure. The company invested SEK168 million during the year, the majority of which was devoted to improvements in quality and capacity at its powder plant in Hoganas, completed in September 1998. In other Hogan& news, the completion of GKN’s acquisition of Hoeganaes Corp means that a new notice of termination of one month has come into effect for the existing R&D agreement between the two powder makers.

P/M Krupp extends materials range for high density process P/M KRUPP Technologies Inc (Chelsea, MI, USA) has added M-4 high-speed steel (HSS) to the range of materials that can be processed to full density with its F2TM process. The company says this is the first time that it has been possible to produce 100% dense PM parts from the steel. The company’s proprietary F2 process involves sintering at higher and more variable temperatures and pressures than conventional sintering, yielding 98-100% dense parts. Materials already successfully processed to full density using the process include T-15, T-15HV, M-42, M-2, D-2 and M-3/2 HSS and various lower alloy steels such as 1080,4180,4280 and 4680, says the company
The demand for speciality cutting tools made from M-4 stock has been growing during the past couple of years, according to Stephanie Krupp, vice president of sales and marketing. “Applying the F2 process to HSS tool blanks into directly translates more efficient processing and for our customers quicker turnaround on special order tools”, she says. “We deliver near-net shape tools with chamfers, chipbreakers and countersunk through-holes, cutting finishing times and allowing our customers to basiready-to-use cally pull parts off the shelf.” PIM Krupp Technologies Inc; tel: +l-734-4754540; fax: +l-734-475-4687.
