Iron Corrosion Properties on Eleven Wood Species

Eleven wood species originated from West Java and East Java were evaluated their metal corrosion properties to iron screw using jam-pot met hods. Wood samples were divided radialfy into three groups, namefy outer, middle and innerpart ef log. Results showed that iron corrosion was found in all wood species. The corrosion intensities were indicated lly the weight loss ef the attached metal screws.Higher corrosion rates werefound on samples of ki biur (Castanopsis acuminatissima A.DC.). The highest weight loss ef screw wasfound, on the innerpart ef ki hiur samples, i.e. 6.89%. The lowest weight loss ef screw was encountered on samples extractedfrom the innerpart ef hum mentek (Lindera polyantha Boeri.).
