[Electric Drive Assembly Designated Orders Landed, Magnesium Alloy Opens Up Incremental Space in Automotive Sector] Recently, the application of magnesium alloy in the lightweighting of NEVs accelerated, with semi-solid die casting and large-scale integrated molding technology becoming the mainstream direction. Orders and capacity for core components such as electric drive housings and auto body structural parts advanced simultaneously.

Recently, the application of magnesium alloys in NEV lightweighting has accelerated, with semi-solid die casting and large-scale integrated forming technologies becoming mainstream directions. Orders and capacity for core components such as electric drive housings and auto body structural parts are advancing in parallel.
Electric Drive Assembly Lightweighting: High-End Applications of Magnesium Alloy Housings
During the 2026 Beijing Auto Show, Xingqu Technology unveiled the TP501, a 900V high performance magnesium-aluminum alloy coaxial dual electric drive assembly, featuring a hard-mold semi-solid magnesium alloy die-cast housing that achieves a 30% weight reduction. It is compatible with high-end NEV car models and has already secured letters of intent from multiple automakers.
Large-Scale Integrated Die Casting: Technological Breakthroughs and Order FulfillmentLeading in technology, mastering unique mold
1 Yian Technology (300328): A leader in magnesium alloy integrated die casting with proprietary tooling processes and semi-solid die casting technology, achieving high yield rates and controllable costs. Its 6,100T large die casting machine is in the client engagement stage, while existing capacity is concentrated in the 650T–4,200T range, with a strategic focus on high-value 1,200T–4,200T production lines. At the end of 2025, the company secured a 430 million yuan magnesium alloy powertrain housing nomination order covering the full lifecycle. Molds and samples have been completed and submitted for validation, with mass production expected in June 2026. In 2026Q1, revenue reached 355 million yuan (+9.29% YoY), with significant growth in the automotive lightweighting business.
2 Chenzhì Lightweighting: On April 8, in collaboration with Changan Automobile, the company successfully produced the first sample from its 5,000T magnesium alloy TPI semi-solid injection molding production line, targeting ultra-large components such as auto body structural parts, tailgate inner panels, and electric drive housings. Compared with traditional high-pressure die casting, this process improves casting mechanical performance by 20% and material utilization rate by 15%, eliminates the smelting process, reduces energy consumption, and addresses the safety issue of magnesium melt oxidation, accelerating NEV lightweighting upgrades.

Magnesium alloys are penetrating from small parts into large structural components and core electric drive parts, with semi-solid die casting becoming the mainstream technology to address traditional die casting defects. OEM high-voltage platform upgrades (e.g., 900V) are further boosting demand for magnesium alloy housings, and 2026 is expected to see a mass production peak.

Transport Costs Keep South African Chrome Producers Under Margin Pressure

[SMM Express] Transport-related costs remain an important cost challenge for South Africa's chrome industry. The Minerals Council South Africa said in its latest Mining Input Cost Inflation report that chrome and manganese experienced elevated input-cost inflation in June, largely due to their reliance on transportation networks, particularly road freight, where higher fuel prices have increased operating costs. The pressure comes alongside elevated energy costs, with the Minerals Council noting that higher fuel prices and the full impact of winter electricity tariffs are expected to keep mining input-cost inflation elevated in the coming months. For chrome producers, the combination of fuel-intensive ore transportation and higher power costs could continue to weigh on margins, particularly for operations dependent on longer road-haulage routes to processing plants and export corridors.

Bengwenyama Moves Closer to Development as South Africa Grants 30-Year Mining Right

[SMM Express] Southern Palladium has secured a 30-year mining right for its Bengwenyama PGM-chrome project on the Eastern Limb of South Africa's Bushveld Complex. The right was granted by the Department of Mineral and Petroleum Resources on August 7, 2026, marking a key regulatory milestone for the development, which is planned to recover both PGMs and chrome from UG2 ore. The development is particularly relevant to the chrome market following recent metallurgical testwork that lifted expected chromite recovery to 85.6%, from the 30%assumption in the earlier pre-feasibility study, potentially raising chrome concentrate production to about 1.054 million mt/y at the planned Stage 2 expansion. The mining right therefore strengthens the pathway for a future additional chrome supply source from South Africa's Bushveld Complex, although the project remains subject to further development and financing milestones.

[SMM Express] Global Chrome Ore Departures Rise 12.68% WoW to 717,000 mt, Led by Maputo

Global chrome ore departures from major export ports totaled 717,000 mt in the week ended August 7, up 12.68% week-on-week, according to SMM's latest data. The increase was primarily driven by Maputo, which handled 496,200 mt, accounting for about 69% of total shipments. Richards Bay followed with 171,500 mt, while Mersin recorded 49,300 mt and Beira reported no chrome ore departures. The latest data also shows a notable shift in weekly flows. Maputo shipments increased from 389,300 mt in the previous week, while Richards Bay shipments eased from 180,400 mt and Mersin shipments declined from 66,600 mt. The stronger overall departures, led by Maputo, point to increased seaborne chrome ore flows from Southern Africa during the latest reporting week, with the port distribution highlighting the continued importance of Mozambique and South Africa's export corridors in global chrome ore supply.
