isostatic pressing sintering polish alumina ceramic bar rod
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
The price of alumina ceramic steel is running low. From January to June 2013, the overall performance of the domestic steel market was sluggish. With the substantial release of crude steel production capacity, market supply and demand have fallen into a state of imbalance, and steel prices have entered a downward channel and have been weakly down for more than four months. As of July 26, 2013, the steel price index fell to 100.48 points, which was lower than 6.6 points at the beginning of the year. The prices of the eight steel products under the key statistics of the Iron and Steel Association have all declined to varying degrees from the beginning of the year, with an average drop of 5.7%. In terms of varieties, the prices of construction wire rod and rebar, which account for a large proportion of my country's steel output, fell by 4.9% and 6.7%, respectively, and the prices of medium and heavy plates and hot rolled coils fell by 5.7% and 9.7%, respectively. Steel exports have grown rapidly. The imbalance between supply and demand in the domestic steel market stimulates corporate exports. From January to June, my country exported 30.69 million tons of steel products, an increase of 12.6% year-on-year; imported steel products were 6.83 million tons, a decrease of 1.8%, and imported steel billets and ingots were 320,000 tons, an increase of 50%. Converting billets into crude steel, the cumulative net export was 25.06 million tons, an increase of 17.3% year-on-year, accounting for 6.4% of my country's crude steel output. In terms of export prices, the average export price of bar and wire from January to June was US$624.3/ton, a year-on-year decrease of 18%; sheet metal was US$835.2/ton, a year-on-year decrease of 2.8%.
