Mauricio Esguerra - Magment

  1. 1. MAGMENT COMPANY PRESENTATION Leonhardsweg 4 - 82008 Unterhaching (Munich) - GERMANY www.magment.de
  2. 2. 2 The Company  Leading specialist in electro-magnetic materials and designs  Founded 2015 based on 27+ years of experience in the industry  Our materials and modules are based on proprietary technology  Main applications ➢ Power inductive components ➢ Wireless power transmission ➢ Induction cooking & heating ➢ Shielding (LF) and EMC (HF) ➢ Electric motors (under development)
  3. 3. 3 Our Team and Partners
  4. 4. 4 What is MAGMENT? • A composite material with soft magnetic grains with a specific particle size distribution embedded in a cement matrix: MAGMENT = MAGnetic ceMENT • High permeability (up to 70) opening up a broad range of electromagnetic applications • No pressing process needed(!) offering many possibilities for cost-leading and size-unlimited parts • Very robust and stable with a long lifetime • Uniquely suitable for mechanically rugged inductive components with high environmental stability
  5. 5. 5 Concrete Properties • Densification by chemical reaction with water • Self-compacting with vibration table • Very small shrinkage (~ 0.5%) • Closed porosity • Water absorption < 1 % • Hardening time can be adjusted • Very high corrosion resistance • High flowability • Adopts any shape and size, e.g. by 3D printing
  6. 6. 6 Raw Materials from Recycling • Soft ferrite scrap ❖ factory rejects ❖ electronic waste • Very low CO2 footprint • No raw material bottleneck for large-scale use • Recycleable CIRCULAR ECONOMY Chemical element Magnetizable concrete omposition rank Earth crust abundance rank Iron 1 4 Manganese 2 12 Zinc 3 24 Calcium 4 5 Aluminium 5 3
