Investment Rating - The investment rating for the tungsten industry is "Outperform the Market" (maintained) [1] Core Viewpoints - The tungsten industry chain extends from exploration and mining of tungsten ore to smelting and deep processing, ultimately applied in various industrial fields. The upstream focuses on black and white tungsten ore, while the midstream involves the smelting of tungsten concentrate, ammonium paratungstate (APT), and tungsten powder. The downstream includes the processing of tungsten materials, tungsten wires, and hard alloys, with demand coming from sectors like machinery manufacturing, automotive, and electronics [2][6] - As of July 23, 2023, the prices for tungsten products have seen significant increases compared to the beginning of the year, with black tungsten concentrate at 185,000 RMB/ton (up 29.4%), APT at 272,000 RMB/ton (up 28.9%), tungsten powder at 405 RMB/kg (up 28.2%), and tungsten carbide powder at 395 RMB/kg (up 27.0%) [2][16] - The supply of tungsten is tightening, with the first batch of mining indicators for 2023-2025 showing a decrease in quotas, leading to expectations of a supply shortage. China's tungsten resources are abundant, holding the world's largest tungsten reserves and production, but total control policies have gradually lowered production levels [2][29] - Demand for tungsten is expected to grow, particularly in the fields of new energy vehicles and military applications, with the APT operating rate at historical highs. The demand for high-end hard alloys is resilient, supporting mid-to-high-end tungsten prices [2][16] - The tungsten supply-demand balance indicates a projected shortage of 2,919 tons in 2025, with prices expected to continue rising. Demand is anticipated to grow at a rate of 4.9% to 6.3% from 2025 to 2027, while supply is expected to increase by only 2,000 tons annually [2][16] - Key companies in the tungsten industry include Xiamen Tungsten, which has a full industry chain layout and is rapidly increasing its photovoltaic tungsten wire production; Zhongtung High-tech, a leader in hard alloys with significant raw material supply advantages; and Zhangyuan Tungsten, which has prominent resource advantages and improved deep processing profitability [2][16] Summary by Sections Tungsten Price Review - The tungsten prices have shown a steady increase over the past five years, correlating positively with PMI [9][12] Supply: Decrease in Mining Indicators - The first batch of mining indicators for 2023-2025 shows a reduction, with 2025's indicators down by 6.45%. This reduction reinforces expectations of a tight supply [2][16] Demand: Growth Driven by Photovoltaic Tungsten Wire - The demand for tungsten is expected to increase, particularly in high-end applications, with a projected consumption of 71,000 tons in 2024, reflecting a growth rate of 3.5% [2][6] Supply-Demand Balance: Expanding Shortage - The tungsten supply-demand balance indicates a growing shortage, with projected deficits increasing from 2,919 tons in 2025 to 9,020 tons by 2027 [2][16] Company Analysis - Xiamen Tungsten is expanding its photovoltaic tungsten wire production, while Zhongtung High-tech is a leader in hard alloys with strong raw material supply advantages [2][16]
