Precious metal - Import export

Titanium is a silvery-white light metal that is often found, but is difficult to extract. In its pure form titanium is easy to form, malleable, thermally relatively stable and very good electrical conductor. Important characteristics are its mechanical strength and low thermal expansion. Titanium is relatively resistant to air at room temperature and its corrosion resistance is comparable to that of precious metals. High-purity titanium is used as a getter metal to remove the last gas residues in vacuum technology, as it reacts with small amounts of oxygen. Corrosion-resistant, pure titanium is used in the construction of chemical plants. Due to their high strength, low weight and excellent corrosion resistance, titanium alloys are excellent construction materials for shipbuilding and the aerospace industry. Titanium is also an important alloying element in special steels.

Rapid developments in the fields of control engineering and in microprocessor and semiconductor technology have resulted in the widespread use of electronically controlled systems in every branch of industry today. This has created a need for sensors that are inexpensive but, at the same time, sufficiently robust, both electrically and mechanically, to withstand a wide range of temperatures (e.g. from -40 to +160 degrees centigrade), particularly in applications involving large quantities, such as the automobile industry. Fig. 1 provides a summary of the various types of sensors for angular and linear motion that are in use today. This paper is concerned with quality criteria (1) and (2) applicable to conductive-plastic potentiometers for use as sensors for angular and linear motion. Such potentiometers essentially comprise the following components: 1. The resistance element (support material + a resistance track of conductive plastic) 2. A wiper (precious metal alloy) 3. A...

As an angle sensor that is both accurate and economical, this rotary potentiometer is suitable for all types of analog angle measurement up to 350°. Typical fields of application include: —Position feedback in servo-systems —Pendulum weighing machines —Cam and butterfly flap positions —Jockey roller controllers —Measuring the tension of threads and tape —Trigonometric measurements at joints The heart of the potentiometric angular displacement sensors is an extremely precise, low-wear resistor track made of plastic. Due to its high resistance to abrasion, the sensors are particularly suitable for measurements for the purpose of quality assurance in ongoing production, where a long service life and large numbers of rotations are required. The potentiometric angular displacement sensor uses a multi-finger slider system with precious metal contacts. This ensures good contact even when moving at high speed and in the presence of vibrations.

Montmorillonite / Bentonite (clay) is a mineral natural product. Due to their crystal structure and molecular components, which are nontoxic harmless biodegradable, they are widely used in the desiccant industry. Biodegradable & harmless Mineral natural product Costeffective Our montmorillonite / bentonite desiccant bags contain water vaporabsorbing, nonwatersoluble desiccant (montmorillonite). Due to the adsorption capacity of montmorillonite, the humidity in the packaging is reduced. This means that we can virtually rule out the risk of moisture damage. Montmorillonite / bentonite is used particularly in areas where strong protection against moisture is required. For example electronic parts, industrial goods or pharmaceutical products. In the automotive sector, too, montmorillonite / bentonite is a classic desiccant that is used here.
