Cast Iron Price Trend

Pig Iron Price = 0.41 USD/kg
Exchange Rate = 6.10 USD to RMB

Price Forecast & Comment

The pig iron prices have reduced some slowly, but the exchange rate of USD to RMB is also reducing too, moreover, the manpower cost in China has increased some in this year. So we think the cast iron prices are still unstable now.
