Why this edge matters
Ningbo Jiangfeng Electronic Material (Konfoong) (leader in Materials) is a tracked supplier of ChangXin Memory (CXMT) (challenger in Memory). China's leading maker of ultra-high-purity sputtering targets (Al, Ti, Ta) for semiconductor metallization. China's domestic DRAM champion, scaling DDR5 and early HBM. The edge is one of 3 tracked suppliers of ChangXin Memory (CXMT) and one of 5 tracked customers of Ningbo Jiangfeng Electronic Material (Konfoong).
Source: derived from both company records and the counted edges.
Concentration / risk note
Ningbo Jiangfeng Electronic Material (Konfoong) is positioned as a leader in Materials, so this edge is harder to replace than a challenger or niche supplier. ChangXin Memory (CXMT) has only 3 tracked suppliers in this dataset. Concentration on the supplier side is high.
Basis: supplier position, few suppliers. Omitted on edges where the graph does not back a concentration claim.
