Copper Development Association at MEDICA 2012 - Antimicrobial copper alloys in high demand

A large crowd had to register the booth of the German Copper Institute at MEDICA 2011: together with construction companies such as the light switch manufacturer Berker GmbH or the hardware firm of Wilhelm May GmbH presented itself to the copper as well as first intermediates manufacturer with a wide range of antimicrobial copper materials.
The semi-finished metal works Diehl, KME Germany AG, MKM Mansfeld copper and brass GmbH and Wieland Werke AG impressed with a large selection of different color schemes - from the warm coppery alloys to stainless steel in appearance - and surface texture.
The positive properties of copper alloys such as high scratch resistance and deformability or longevity are also rediscover the antimicrobial alloys, which opens the users a wide range of applications. Accordingly, the visitors were interested in the stand. In addition to physicians, hospital architects, medical product and furniture manufacturers found themselves a sizeable number of operators of hospitals and nursing homes and health professionals to obtain information about the antimicrobial properties of copper alloys as a further building block in the standard hygiene measures.

Apple has secured rights to use new materials

U.S. computer manufacturer Apple has reportedly secured exclusive rights to use the metal by the U.S. specialists Liquidmetal Technologies developed materials. According to a mandatory reporting of Liquid Metal to the U.S. Securities and Exchange Commission, Apple has acquired for an undisclosed sum for the exclusive Lizenrechte field of consumer electronics, among others reported the U.S. newspaper Baltimore Sun. Existing agreements with manufacturers of the metal specialist sports equipment and medical equipment and defense companies are not affected by the license agreement.

Heater Tube Failures relating to metal alloys

25.2 Heater Tube Failures
Heater tubes are designed to operate at a particular pressure an temperature. The design pressure of the tube is not the inlet operating pressure of the heater. The design tube pressure is the heater charge pump dead-head, or shut-in, pressure, as discussed in Chap. 29. The design temperature of the tube is not the heater outlet process operating temperature. The design tube temperature is the anticipated or calculated maximum tube skin temperature (at end-of-run conditions), which is simply the temperature of the exterior metal surface of the tube. Many plants call this temperature the tube metal indication (TMI).
The calculated tube skin temperature is mainly a function of the fouling resistance assumed inside the tube. The greater the assumed fouling resistance, the higher the design tube skin temperature, and the thicker the tube wall. In a sense, then, we partially assume the design tube thickness, on the basis of experience, for a particular plant service.
A typical process heater tube diameter is 4 to 10 in. Tube thickness is usually between 0.25 and 0.50 in. Heater tubes are often constructed
out of chrome steel. A high chrome content is 13 percent. The chrome content increases the heat resistance of the tube. A tube with a 11 to 13 percent chrome content can normally withstand a skin temperature of up to 1300 to 1350°F. A low-chrome-content tube of perhaps 3 percent may be limited to 1200°F tube metal temperature. Naturally, the pressure, thickness, and diameter of the tube, all affect its maximum

ferro alloys

We are looking for more suppliers of ferro alloys like ferro-manganese, ferro-chrome and ferro-nickels.

The 2003 World Forecasts of Ferro-Alloys Export SuppliesThis report was created for strategic planners, international marketing executives and export managers whose primary concern is the world market for ferro-alloys. With the globalization of this market, managers can no longer be contented with a local view. Nor can managers be contented with out-of-date statistics that appear several years after the fact. I have developed a methodology, based on macroeconomic and trade models, to estimate the market for ferro-alloys for those firms serving the world via exports and foreign direct investment. It does so for the current year based on a variety of key historical indicators and econometric models.
