Cargill was able to increase the cost by 10 percent to $63.27 per ton for up to 140 percent of the amount; over that, the company charged market price, $82.71 per ton. If a salt delivery was late, the contract allowed municipalities to withhold 50 cents per ton, per day as damages. Delivery woes this past winter.
White tin is the normal form of the metal and has many uses. Unfortunately, white tin will turn into gray tin if its temperature falls below 13.2Â°C. This change can be prevented if small amounts of antimony or bismuth are added to white tin. Tin resists corrosion and is used as a protective coating on other metals. Tin cans are probably the most familiar example of this application. A tin can is actually made from steel.
Tungsten and its alloys are widely used for filaments in older style (not energy saving) electric bulbs and electronic tubes. It is used for making heavy metal alloys because of its hardness. Tungsten is used for high-temperature applications such as welding. High speed steel (which can cut material at higher speeds than carbon steel), contains up to 18% tungsten. Tungsten carbide (WC or W 2 C) is extremely hard and is used to make drills.
